Clinical evaluation of Boswellia serrata (Shallaki) resin in the management of Sandhivata (osteoarthritis)

Efficacy and safety evaluation of Boswellia serrata and Curcuma longa extract combination in the management of chronic lower back pain: A randomised, double-blind, placebo-controlled clinical study

BACKGROUND AND AIM

Chronic lower back pain (CLBP) is a major condition that leads to disability and reduced quality of life (QoL). This randomised, double-blind, placebo-controlled clinical study evaluated the efficacy and safety of a novel Boswellia serrata and Curcuma longa combination (CL20192) for the treatment of CLBP.

MATERIAL AND METHODS

Participants with CLBP were randomised to receive either a 300 mg CL20192 capsule (n = 45) or placebo capsule (n = 45) once daily for 90 days. Efficacy was evaluated using the Descriptor Differential Scale and Oswestry Disability Index scores for pain, unpleasantness, and disability. Additionally, the 36-item short form questionnaire was used for QoL evaluation. Frequency of painkiller use, serum levels of inflammatory biomarkers (tumour necrosis factor-α, interleukin-6, and high-sensitivity C-reactive protein), and phytoconstituents (total boswellic acids and curcuminoids) were determined. Therapy satisfaction was assessed using the Physician and Patient Global Assessment Scales.

RESULTS

All randomised participants completed the study. CL20192 supplementation significantly reduced Descriptor Differential Scale pain, unpleasantness, and Oswestry Disability Index scores compared with the placebo group (p < 0.001 for all parameters). Critical QoL scores greatly improved in the CL20192 group. Serum phytoconstituent levels were elevated in the CL20192-treated group. This group demonstrated a significant reduction in inflammatory biomarker levels (tumour necrosis factor-α, interleukin-6, and high-sensitivity C-reactive protein), confirming efficacy in abating CLBP compared with the placebo. Moreover, therapy satisfaction scores were significantly high in the CL20192-treated group, and intervention with CL20192 was well tolerated.

CONCLUSION

Intervention with 300 mg CL20192 capsules, containing a novel combination of Boswellia serrata and Curcuma longa extracts, effectively alleviated pain, unpleasantness, and disability in patients with CLBP compared with the placebo. This outcome was consistent with a decrease in serum inflammatory markers and improved therapy assessment scores.

Bioactive Compounds in Osteoarthritis: Molecular Mechanisms and Therapeutic Roles

Osteoarthritis (OA) is the most common and debilitating form of arthritis. Current therapies focus on pain relief and efforts to slow disease progression through a combination of drug and non-drug treatments. Bioactive compounds derived from plants show significant promise due to their anti-inflammatory, antioxidant, and tissue-protective properties. These natural compounds can help regulate the inflammatory processes and metabolic pathways involved in OA, thereby alleviating symptoms and potentially slowing disease progression. Investigating the efficacy of these natural agents in treating osteoarthritis addresses a growing demand for natural health solutions and creates new opportunities for managing this increasingly prevalent age-related condition. The aim of this review is to provide an overview of the use of some bioactive compounds from plants in modulating the progression of osteoarthritis and alleviating associated pain.

A standardized Boswellia serrata extract shows improvements in knee osteoarthritis within five days-a double-blind, randomized, three-arm, parallel-group, multi-center, placebo-controlled trial

Background

Boswellin® Super is a standardized extract of Boswellia serrata Roxb gum resin, standardized to contain 30% 3-acetyl-11-keto-β-boswellic acid along with other β-boswellic acids (BSE). A randomized, double-blind, placebo-controlled clinical trial was conducted at two doses of BSE to understand its safety and efficacy in supporting joint health and improving mobility and symptoms of osteoarthritis (OA) of the knee.

Methods

Based on the inclusion/exclusion criteria, 105 newly diagnosed participants with degenerative hypertrophy OA were recruited and randomized into Placebo, BSE-150 mg or BSE-300 mg (n = 35 in each group) to receive either 150 mg or 300 mg BSE or a placebo tablet twice a day for 90 days. All the participants were evaluated for pain and physical function using the standard tools including the Visual Analog Scale (VAS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lequesne Functional Index (LFI), EuroQol- 5 Dimension (EQ-5D) quality of life, 6-min walk test at day 0, days 5, 30, 60 and 90 of treatment. Additionally, the circulating levels of inflammatory biomarkers, tumor necrosis factor-α (TNFα), high-sensitive C-reactive protein (hs-CRP), and interleukin-6 (IL-6) were evaluated. Safety was evaluated by blood biochemical, hematological analysis, urinary analyses and by monitoring adverse events throughout the study.

Results

Ninety-eight subjects completed the study. Improvements in pain scores were observed as early as 5 days after the start of the supplement in the BSE-150 and BSE-300 groups. By 90 days, the VAS pain score reduced by 45.3% and 61.9%, WOMAC- total score improved by 68.5% and 73.6% in the BSE-150 and BSE-300 groups respectively. WOMAC pain (70.2%, 73.9%, WOMAC stiffness (65.6%,68.9%), WOMAC function (68.8%,74.2%), LFI severity (50%,53.3%), decreased and EQ5D (56.9%, 62.9%) and distance walked in 6 minutes (21.2%, 21.9%) improved in the BSE-150 and BSE-300 groups in 90 days. Further, the levels of TNFα, hs-CRP, and IL-6 were found to decrease in the serum in BSE-supplemented participants. No significant adverse events were recorded during the study.

Conclusion

The study confirms that Boswellin® Super can be used as a safe and effective supplement to support joint health and mobility in the management of osteoarthritis.

The effect of back massage with frankincense and myrrh oil before the cardiac electrophysiological procedure on back pain intensity and comfort: A single-blind randomized controlled trial

CONTEXT

Back pain is one of the most common problems experienced by patients after the cardiac electrophysiological study procedure. In addition, limitation of movement after the procedure negatively affects the comfort and satisfaction of patients.

OBJECTIVES

The aim of this study was to determine the effect of back massage with frankincense and myrrh oil on back pain severity and comfort in patients who were to undergo cardiac electrophysiological study.

METHODS

This is a randomized controlled study with a pretest-posttest design. This study was conducted from October 2020 to March 2021, at the angio unit of a heart hospital at a university in Turkey. The study was completed with 30 patients in each group, a total of 90 people. Data were collected using a patient information form, a Visual Analogue Scale (VAS) and the General Comfort Questionnaire (GCQ). The intervention group and the placebo group received back massage with frankincense and myrrh essential oil and with jojoba fixed oil respectively. No intervention was applied to the control group.

RESULTS

There was no statistically significant difference between the post-procedure VAS values according to the groups. Except for sociocultural comfort, there were significant differences between the groups in terms of GCQ total scores and subscales at the first and last follow-up.

CONCLUSIONS

Back massage with frankincense and myrrh oil increased overall comfort, physical comfort, the psychospiritual comfort. Additional research with a rigorous design is needed to determine its effect on pain.

Ingredients of a Natural Oral Nutritional Supplement and Their Role in the Treatment of Osteoarthritis

Osteoarthritis is a prevalent degenerative disease affecting a large portion of the world’s aging population. Currently, nonsteroidal anti-inflammatory drugs and acetaminophen are first-line medications for treating osteoarthritis patients’ pain. However, several studies have noted that while these medications control pain they do not halt progressive degeneration and tend to have an unfavorable side-effect profile with prolonged use. Recently, due to their more favorable side-effect profiles, herbal alternatives for controlling osteoarthritis symptoms and for alleviating the progression of the disease are being increasingly studied. Synogesic is a newly developed herbal supplement blend by renowned orthopedic surgeons and physiatrists consisting of turmeric, rutin, ginger root, vitamin C, vitamin D, and boswellia extracts. A study by Sharkey et al. has commented on the efficacy of the blend on the patients with knee osteoarthritis. So far, a review on the ingredients of the blend has not yet carried outbeen. By exploring prominent literature databases including PubMed and ScienceDirect, our aim is to write a narrative review to explore the individual ingredients of this blend and delve into their characteristics, as well as the most recent literature on their mechanism and efficacy in patients with osteoarthritis. Through this, we hope to inform clinicians and patients alike on relevant up-to-date research on the supplement and provide insight on the potential for this supplement for alleviating the disease course of patients with osteoarthritis.

Pharmacokinetics of solid lipid Boswellia serrata particles in healthy subjects

OBJECTIVES

The anti-inflammatory activity of Boswellia serrata extracts (BSE) is well known. BSE comprises boswellic acids (BA) such as 3-O-acetyl-11-keto-beta-boswellic acid (AKBA) and 11-keto-boswellic acid (KBA) as major constituents. One of the limitations of BAs is their poor oral bioavailability. The aim of the study was to prepare solid lipid particles of Boswellia serrata extract (SLBSP) to enhance the bioavailability of BAs.

METHODS

The pharmacokinetic profile of BAs was studied in 10 healthy human volunteers following a single oral dose of 333 mg of SLBSP. Pharmacokinetic blood samples were collected at 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 12 h post drug administration. Plasma KBA and AKBA levels were measured using a validated LC-MS/MS method. Pharmacokinetics parameters were estimated using Pheonix WinNonlin (Build 6.4.0.768) software.

RESULTS

Ten healthy human volunteers were included and peak plasma concentration was achieved in 1.5 and 2.3 h for AKBA and KBA respectively. Maximum plasma concentration (C max) was 8.04 ± 1.67 ng/mL for AKBA and 23.83 ± 4.41 ng/mL for KBA whereas the corresponding area under the concentration-time curve (AUC) was 136.7 ± 56.77 ng/mL*h and 165.7 ± 24.5 ng/mL*h respectively. The elimination half-life (t 1/2) of AKBA and KBA was 6.8 ± 3.0 h and 2.45 ± 0.3 h respectively.

CONCLUSIONS

The SLBSP formulation of BSE showed enhanced oral bioavailability of BAs compared with historically reported data of unformulated BSE.

Clusters of Responders and Predictive Factors for Response to Supplementation with Boswellia, Turmeric, and Red Algae Extracts in Painful Knee Osteoarthritis: A Prospective Observational Study Using an Arsenal of Patient-Centered Measures

Purpose

This observational study evaluated a combination of boswellia, turmeric, and red algae extracts in patients with knee osteoarthritis (KOA). Given the growing interest in patient-centered care in osteoarthritis, effects were assessed by an arsenal of patient-reported outcome measures (PROMs): Patient Acceptable Symptom Scale (PASS), Minimal Clinically Important Improvement (MCII), Patient Global Impression of Change (PGIC), and Lequesne algofunctional index (LAFI). Patients also completed a list of 17 items on pain quality.

Patients and Methods

Patients with painful unilateral or bilateral KOA had to take 1-4 capsules per day of a dietary supplement containing boswellia, turmeric, and red algae extracts for 90 days. Patients completed PROMs on Days 0 (baseline), 10, 20, 30, 60, and/or 90.

Results

A total of 118 patients [female: 69.5%; age: 62.9 (9.5) years, mean (SD)] were included in the study and took at least one capsule. Mean (SD) follow-up duration was 100.7 (54.9) days. Pain relief was maximal on Day 90: 64.5% of patients were responders (positive PASS); 68.8% and 58.4% had MCII and PGIC scores indicating positive effect (score ≥3) or global improvement (score ≥5); 73.3% (versus 47.5% at baseline) were mildly/moderately disabled (LAFI score <8); 55.2% had meaningful decrease (-30%) in pain intensity (VAS), 35.1% (versus 59.2% at baseline) took analgesics as supplementary treatment. Median time to the first PASS change was 34 days. Pain intensity (VAS), as well as two pain characteristics (ie, "Stabbing pain" and "Widespread pain"), were independent factors associated with non-response on Day 30. Four clusters of responders were isolated according to pain characteristics, with one cluster exhibiting a higher responder rate.

Conclusion

The results of this preliminary study suggest that the combination of boswellia, turmeric, and red algae extracts tested could improve KOA patients. Beyond these results, this study showed the importance of PROMs and specific pain qualitative descriptors for the accurate evaluation of dietary supplement approaches in painful conditions.

Effectiveness of Boswellia and Boswellia extract for osteoarthritis patients: a systematic review and meta-analysis

Background

Osteoarthritis (OA) is the commonest form of inflammatory joint disease. Unfortunately, to date, there is no appropriate treatment for OA. Boswellia serrata was considered as a potent anti-inflammatory, anti-arthritic and analgesic agent that may be a drug for OA.

Methods

In this meta-analysis, data from randomized controlled trials were obtained to assess the effects of Boswellia or its extract versus placebo or western medicine in patients with OA. The primary outcomes included visual analogue score (VAS), WOMAC pain, WOMAC stiffness, WOMAC function and lequesne index.

Result

Seven trials involving 545 patients were included. Compared with the control group, Boswellia and its extract may relieve the pain [VAS: (WMD -8.33; 95% CI -11.19, − 5.46; P<0.00001); WOMAC pain: (WMD -14.22; 95% CI -22.34, − 6.09; P = 0. 0006)] and stiffness [WOMAC stiffness: (WMD -10.04; 95% CI -15.86, − 4.22; P = 0. 0007)], and improve the joint’s function [WOMAC function: (WMD -10.75; 95% CI -15.06, − 6.43; P<0. 00001); lequesne index: (WMD -2.27; 95% CI -3.08, − 1.45; P<0. 00001)].

Conclusion

Based on current evidence, Boswellia and its extract may be an effective and safe treatment option for patient with OA, and the recommended duration of treatment with Boswellia and its extract is at least 4 weeks.

An Anti-Inflammatory Composition of Boswellia serrata Resin Extracts Alleviates Pain and Protects Cartilage in Monoiodoacetate-Induced Osteoarthritis in Rats

The boswellic acids, the active compounds in Boswellia serrata gum resin extract, are potent anti-inflammatory agents and are specific nonredox inhibitors of 5-Lipoxygenase (5-LOX). Here, we present the anti-osteoarthritis (OA) efficacy of LI13019F1 (also known as Serratrin®), a unique composition containing the acidic and nonacidic fractions of B. serrata gum resin. This composition strongly inhibited 5-LOX activity with the half-maximal inhibitory concentration (IC₅₀) of 43.35 ± 4.90 μg/mL. Also, LI13019F1 strongly inhibited the leukotriene B₄ (IC₅₀, 7.80 ± 2.40 μg/mL) and prostaglandin E₂ (IC₅₀, 6.19 ± 0.52 μg/mL) productions in human blood-derived cells. Besides, LI13019F1 reduced TNF-α production with the IC₅₀ of 12.38 ± 0.423 μg/mL. On average, 1, 2.5, and 5 μg/mL doses of LI13019F1 protected 34.62, 47.66, and 62.29% SW1353 human chondrosarcoma cells from IL-1β induced SOX-9 depletion, respectively. Further, a 28-day preclinical proof-of-concept study evaluated the pain relief efficacy of LI13019F1 in monoiodoacetate- (MIA-) induced Sprague-Dawley rats. At the end of the study, 150 and 300 mg/kg doses of LI13019F1 supplemented rats showed significant improvements (55.17 ± 5.81 g (p < 0.05), and 66.22 ± 6.30 g (p < 0.05), respectively, vs. MIA: 31.22 ± 7.15 g) in body-weight-bearing capacities. Concurrently, LI13019F1-150 and LI13019F1-300 rats substantially (p < 0.05) increased the threshold of pain sensitivity to pressure (26.98 ± 2.36 and 28.06 ± 2.72-gram force, respectively; vs. 18.63 ± 5.82 in MIA) and increased (p < 0.05) the latent time to withdraw the paw after a thermal stimulus (23.61 ± 2.73 and 28.18 ± 1.90 sec, respectively; vs. 16.56 ± 1.22 sec. in MIA). Besides, the histological observations on Safranin-O green stained articular cartilage revealed that LI13019F1 also prevented the MIA-induced structural damage of the cartilage and reduced the loss of the extracellular matrix (ECM) components in the experimental rats. In conclusion, the present observations suggest that LI13019F1, a new composition of B. serrata gum resin extracts, reduces pain and protects articular cartilage from the damaging action of MIA in a rodent model.

Review of health-care services for older population in India and possibility of incorporating AYUSH in public health system for geriatric care

Background:

In a developing country like India, which has 10.11% population of >60 years age and a projection of rise of the same by 300% in 2050, health care of elderly is an enormous challenge. The developed world has evolved many models for elderly care, for example, nursing home care, health insurance, etc. Indian Government has also taken multiple measures in this direction by initiating National Policy on Older Persons, 1999, the Maintenance and Welfare of Parents and Senior Citizens Act, 2007, the Old Age Pension Scheme, Rashtriya Vayoshri Yojana 2017, etc. However, there is a necessity that, India must rapidly adapt to the complex health related, social and economic challenges caused by these demographic changes. This may be an opportunity for innovation in the health system by developing a perspective for healthy and active aging, though it is a major challenge. Health care of the older people cannot be achieved unless total health, i.e., physical, social, economic, psychological, and spiritual aspects are addressed.

Objective:

The objective is to study current policies regarding geriatric health care in India and to propose the possibility to develop a model to provide comprehensive and dedicated health-care services to the older population by integrating conventional and indigenous systems of medicine dwelling in the country.

Materials and methods:

Electronic search in various scientific journals for research and review articles; electronic along with hand searching of conference proceedings, brochures, government policy documents, press releases, Ayurveda classical texts, etc., regarding geriatric health care in India and model health-care facilities in other countries and regarding of AYUSH systems in geriatric health care in India.

Results:

There is an urgent need of adaptation and modification in the National Health System to cater the actual requirements of the elderly with plans and strategies dedicated to face their health-related challenges. Adoption of inclusive health-care interventions, can improve health outcomes by making it more acceptable, accessible, and affordable.

Conclusion:

Integration of AYUSH at various levels of health-care delivery system can potentially contribute to provide unique newer dimensions to the field of geriatric care in India.

Role of Jumpstart Nutrition®, a Dietary Supplement, to Ameliorate Calcium-to-Phosphorus Ratio and Parathyroid Hormone of Patients with Osteoarthritis

The aim of this study was to use Jumpstart Nutrition^® bone supplementing combination with vitamin-K₂ and coenzyme-Q₁₀ characterized by an innovative delivery system that improves bioavailability of calcium-to-phosphorus ratio (CPR) and parathyroid hormone (PTH) in the management of osteoarthritis (OA). This eight-week registry included 108 patients treated for symptomatic OA confirmed with radiological images. On top of that, 63 patients used Jumpstart Nutrition^® supplement, mainly prepared with calcium, phosphorus, coenzyme-Q₁₀, vitamin-K₂, vitamin-D₂, vitamin-C, folic acid, curcumin and boswellic acids. Rescue medication was also recommended. Patients’ pain and functional capacity through outcome measures—knee-injury osteoarthritis outcome scale (KOOS) and Karnofsky performance scale (KPS), biomarkers such as levels of CPR, PTH and 25-hydroxy-vitamin-D were evaluated for the groups with and without supplement using appropriate kits. After eight weeks, the levels of CPR and PTH were all significantly improved (p < 0.001), fewer subjects had to use rescue medication (p < 0.05) and variation of pain and functional capacity under KOOS and KPS (p < 0.05) of the patients in the supplement group compared to controls. This registry study indicates that Jumpstart Nutrition^® can be used safely for effective management of OA patients for the amelioration of CPR, PTH and functional activities confirmed with biomarkers and radiological images correlated with the Kellgren-Lawrance scale.

A pilot, randomized, double-blind, placebo-controlled trial to assess the safety and efficacy of a novel Boswellia serrata extract in the management of osteoarthritis of the knee

A double-blind, placebo-controlled human trial was conducted to evaluate the safety and efficacy of a standardized oral supplementation of Boswellin®, a novel extract of Boswellia serrata extract (BSE) containing 3-acetyl-11-keto-β-boswellic acid (AKBBA) with β-boswellic acid (BBA). A total of 48 patients with osteoarthritis (OA) of the knee were randomized and allocated to the BSE and placebo groups for intervention. Patients were administered BSE or placebo for a period of 120 days. The trial results revealed that BSE treatment significantly improved the physical function of the patients by reducing pain and stiffness compared with placebo. Radiographic assessments showed improved knee joint gap and reduced osteophytes (spur) confirming the efficacy of BSE treatment. BSE also significantly reduced the serum levels of high-sensitive C-reactive protein, a potential inflammatory marker associated with OA of the knee. No serious adverse events were reported. This is the first study with BSE conducted for a period of 120 days, longer than any other previous clinical trial on patients with OA of the knee. The findings provide evidence that biologically active constituents of BSE, namely, AKBBA and BBA, act synergistically to exert anti-inflammatory/anti-arthritic activity showing improvement in physical and functional ability and reducing the pain and stiffness.

Efficacy and safety of curcumin and its combination with boswellic acid in osteoarthritis: a comparative, randomized, double-blind, placebo-controlled study

Background

The aim of this clinical trial was to assess the efficacy and safety of curcuminoid complex extract from turmeric rhizome with turmeric volatile oil (CuraMed®) and its combination with boswellic acid extract from Indian frankincense root (Curamin®) vs placebo for the treatment of 40- to 70-year-old patients with osteoarthritis (OA).

Methods

The effects of CuraMed® 500-mg capsules (333 mg curcuminoids) and Curamin® 500-mg capsules (350 mg curcuminoids and 150 mg boswellic acid) taken orally three times a day for 12 weeks in 201 patients was investigated in a three-arm, parallel-group, randomized, double-blinded, placebo-controlled trial. Primary outcome efficacy measures included OA physical function performance-based tests, the WOMAC recommended index of joint pain, morning stiffness, limitations of physical function, and the patients’ global assessment of disease severity.

Results

Favorable effects of both preparations compared to placebo were observed after only 3 months of continuous treatment. A significant effect of Curamin® compared to placebo was observed both in physical performance tests and the WOMAC joint pain index, while superior efficacy of CuraMed vs placebo was observed only in physical performance tests. The effect size compared to placebo was comparable for both treatment groups but was superior in the Curamin® group. The treatments were well tolerated.

Conclusions

Twelve-week use of curcumin complex or its combination with boswellic acid reduces pain-related symptoms in patients with OA. Curcumin in combination with boswellic acid is more effective. Combining Curcuma longa and Boswellia serrata extracts in Curamin® increases the efficacy of OA treatment presumably due to synergistic effects of curcumin and boswellic acid.

Antioxidant Supplements and Gastrointestinal Diseases: A Critical Appraisal

The gastrointestinal tract digests and absorbs dietary nutrients, protects the body against physical and chemical damage from contents in its lumen, provides immunity against external antigens, and keeps an optimum environment for the gut microbiota. These functions cannot be performed normally in several diseases of which the following are discussed here: irritable bowel syndrome and inflammatory bowel disease, which includes Crohn's disease and ulcerative colitis. Because these diseases are associated with oxidative stress, a host of antioxidant supplements are used for maintenance and recovery of the gut functions. However, the benefits of these supplements have not been established. The available 80 human trials were rated for levels of confidence and for benefits of the antioxidant supplements. For Crohn's disease, the supplements for which clear benefits occurred in at least 2 studies were allopurinol, Boswellia serrata (frankincense or shallaki), Artemesia species (wormwood), Tripterygium wilfordii (léi gōng téng), and omega-3 fatty acids. Similar beneficial supplements for ulcerative colitis were allopurinol, Matricaria chamomilla (chamomile), Curcuma longa (curcumin in turmeric), and omega-3 fatty acids. There was also a clear benefit for ulcerative colitis in 2 studies where a multiherbal Chinese medicine preparation and an Ayurvedic medicine preparation were used. For irritable bowel syndrome, there was only a marginal benefit of some of the antioxidant supplements. Thus, some antioxidant supplements may be beneficial at certain stages of specific diseases. This is consistent with the current concept that antioxidants act by inhibiting oxidative stress pathways in a tissue- and environment-specific manner and not by simply acting as scavengers.

Benefits of antioxidant supplements for knee osteoarthritis: rationale and reality

Arthritis causes disability due to pain and inflammation in joints. There are many forms of arthritis, one of which is osteoarthritis whose prevalence increases with age. It occurs in various joints including hip, knee and hand with knee osteoarthritis being more prevalent. There is no cure for it. The management strategies include exercise, glucosamine plus chondroitin sulfate and NSAIDs. In vitro and animal studies provide a rationale for the use of antioxidant supplements for its management. This review assesses the reality of the benefits of antioxidant supplements in the management of knee osteoarthritis. Several difficulties were encountered in examining this issue: poorly conducted studies, a lack of uniformity in disease definition and diagnosis, and muddling of conclusions from attempts to isolate the efficacious molecules. The antioxidant supplements with most evidence for benefit for pain relief and function in knee osteoarthritis were based on curcumin and avocado-soya bean unsaponifiables. Boswellia and some herbs used in Ayurvedic and Chinese medicine may also be useful. The benefits of cuisines with the appropriate antioxidants should be assessed because they may be more economical and easier to incorporate into the lifestyle.

Management strategies for Janu Sandhigata Vata vis-a-vis osteoartheritis of knee: A narrative review

INTRODUCTION

Ayurveda has described about the pathogenesis and the treatment of various disorders, the incidence of some of which have increased in the present scenario. Janu Sandhigata Vata correlated with osteoarthritis (OA) of the knee joint is one such chronic, degenerative, inflammatory disease which has a great impact on the quality of the life of an individual. Different modalities of treatment have been explained in the classics to tackle the condition effectively.

METHODOLOGY

In the present study, an attempt has been made to review the various clinical research works done in the management of OA of the knee, which are registered in various research portal. In AYUSH Research Portal using the keywords Ayurveda-clinical research-musculoskeletal disorders-osteoarthrosis of knee-Janu Sandhigata Vata and in PubMed using clinical research - Ayurveda-OA. The studies reviewed were categorized depending on the treatment used in the management of the condition.

RESULTS

Fifty three research works were registered under AYUSH Research Portal with 34 full papers. There were 12 research papers in PubMed, out of which 6 papers which dealt with OA of the knee were reviewed. Among these six, three already existed in AYUSH Research Portal. The results were discussed by categorizing the studies as per the treatment used.

CONCLUSION

Among the papers reviewed, most of them dealt with few modalities of treatment rather than the complete classical line of the treatment. The evidence-based research involving multimodality treatment with long-term follow-up covering various aspects of prevention and cure has to be conducted which is the need of the hour.

A randomized, double blind, placebo controlled, cross over study to evaluate the analgesic activity of Boswellia serrata in healthy volunteers using mechanical pain model

OBJECTIVE

Experimental pain models in human healthy volunteers are advantageous for early evaluation of analgesics. All efforts to develop nonsteroidal anti-inflammatory drugs (NSAIDs) which are devoid of gastrointestinal and cardiovascular system effects are still far from achieving a breakthrough. Hence we evaluated the analgesic activity of an ayurvedic drug, Boswellia serrata by using validated human pain models which has shown its analgesic activity both in-vitro and preclinical studies to evaluate the analgesic activity of single oral dose (125 mg, 2 capsules) of Boswellia serrata compared to placebo using mechanical pain model in healthy human subjects.

MATERIALS AND METHODS

After taking written informed consent, twelve healthy subjects were randomized (1:1) to receive single oral dose of Boswellia serrata (Shallaki (®)) 125 mg, 2 capsules or identical placebo in a crossover design. Mechanical pain was assessed using Ugo basile analgesymeter (by Randall Selitto test) at baseline and at 1 hr, 2 hrs and 3 hrs after test drug administration. Pain Threshold force and time and Pain Tolerance force and time were evaluated. Statistical analysis was done by paired t-test.

RESULTS

Twelve healthy volunteers have completed the study. Mean percentage change from baseline in Pain Threshold force and time with Boswellia serrata when compared to placebo had significantly increased [Force: 9.7 ± 11.0 vs 2.9 ± 3.4 (P = 0.05) and time: 9.7 ± 10.7 vs 2.8 ± 3.4 (P = 0.04)] at third hr. Mean Percentage change from baseline in Pain Tolerance force and time with Boswellia serrata when compared to placebo had significantly (P ≤ 0.01) increased at 1 hr, 2 hrs and 3 hrs.

CONCLUSION

In the present study, Boswellia serrata significantly increased the Pain Threshold and Pain Tolerance force and time compared to placebo. Both study medications were well tolerated. Further multiple dose studies may be needed to establish the analgesic efficacy of the drug.

Nutraceuticals: potential for chondroprotection and molecular targeting of osteoarthritis

Osteoarthritis (OA) is a degenerative joint disease and a leading cause of adult disability. There is no cure for OA, and no effective treatments which arrest or slow its progression. Current pharmacologic treatments such as analgesics may improve pain relief but do not alter OA disease progression. Prolonged consumption of these drugs can result in severe adverse effects. Given the nature of OA, life-long treatment will likely be required to arrest or slow its progression. Consequently, there is an urgent need for OA disease-modifying therapies which also improve symptoms and are safe for clinical use over long periods of time. Nutraceuticals-food or food products that provide medical or health benefits, including the prevention and/or treatment of a disease-offer not only favorable safety profiles, but may exert disease- and symptom-modification effects in OA. Forty-seven percent of OA patients use alternative medications, including nutraceuticals. This review will overview the efficacy and mechanism of action of commonly used nutraceuticals, discuss recent experimental and clinical data on the effects of select nutraceuticals, such as phytoflavonoids, polyphenols, and bioflavonoids on OA, and highlight their known molecular actions and limitations of their current use. We will conclude with a proposed novel nutraceutical-based molecular targeting strategy for chondroprotection and OA treatment.
