Ammon HPT. Boswellic extracts and 11-keto-ß-boswellic acids prevent type 1 and type 2 diabetes mellitus by suppressing the expression of proinflammatory cytokines. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 63:153002. [PMID: 31301539 DOI: 10.1016/j.phymed.2019.153002] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Revised: 06/26/2019] [Accepted: 06/27/2019] [Indexed: 05/21/2023]
Abstract
BACKGROUND Type 1 diabetes is an autoimmune disease directed to the pancreatic islets where inflammation leads to the death of insulin-producing ß cells and insulin deficiency. Type 2 diabetes, which is closely related to overweight, is characterized by insulin resistance. In both cases, proinflammatory cytokines play an important role by causing insulitis and insulin resistance. The gum resin of Boswellia species and its pharmacologically active compounds, including 11-keto-ß-boswellic acids have been shown to suppress the expression of proinflammatory cytokines in various immune-competent cells. PURPOSE To review the present evidence of the therapeutic effects of boswellic extracts (BE) and/or 11-keto-ß-boswellic acids in the prevention/treatment of diabetes mellitus and to provide comprehensive insights into the underlying molecular mechanisms. METHODS This review considers all available informations from preclinical and clinical studies concerning BEs, 11-keto-ß-boswellic acids, proinflammatory cytokines and diabetes mellitus collected via electronic search (PubMed) and related publications of the author. RESULTS Type 1 diabetes: Studies in mice with autoimmune diabetes revealed that in the model of multiple injections of low doses of streptozotocin (MLD-STZ), an extract of the gum resin of Boswellia serrata and 11-keto-ß-boswellic acid (KBA) suppressed the increase in proinflammatory cytokines in the blood, infiltration of lymphocytes into pancreatic islets and increase in blood glucose. In a second model, i.e. the nonobese diabetic (NOD) mouse, KBA prevented the infiltration of lymphocytes into pancreatic islets. Regarding the clinical effects, a case report provided evidence that BE suppressed the blood levels of tyrosine phosphatase antibody (IA2-A), a marker for insulitis, in a patient with late-onset autoimmune diabetes of the adult (LADA). Type 2 diabetes: In a preclinical study in rats where obesity was alimentary induced, the administration of BE significantly reduced food intake, overweight, proinflammatory cytokines such as interleukin-1ß (IL-1ß), and tumor necrosis factor-α (TNF-α) and ameliorated the parameters of glucose and lipid metabolism. Similar results were obtained in a second animal study, where type 2 diabetes was induced by a combination of a high-fat/high-fructose diet and a single dose of streptozotocin. Two clinical trials with patients with type 2 diabetes receiving the resin of Boswellia serrata demonstrated improvement in the blood glucose, HbA1c and lipid parameters. CONCLUSION Preclinical and clinical data suggest that BE and/or 11-keto-ß-boswellic acids by inhibiting the expression of proinflammatory cytokines from immune-competent cells, may prevent insulitis and insulin resistance in type 1 and type 2 diabetes, respectively, and therefore may be an option in the treatment/prevention of type 1 and type 2 diabetes. It is hypothesized that molecularly, BE and 11-keto-ß-boswellic acids act via interference with the IκB kinase/Nuclear Transcription Factor-κB (IKK/NF-κB) signaling pathway through inhibition of the phosphorylation activity of IKK. However, further investigations and well-designed clinical studies are required.

Abstract
Background Boswellia carteri Bridw. is being widely used for its anti-inflammatory properties, as well as for wound healing, antimicrobial, and immunomodulatory properties, and boswellic acids (BAs) are considered to be the main active constituents. Objectives To investigate optimal conditions of stir-baking process for the resin of B. carteri with vinegar of using response surface methodology (RSM). Materials and Methods The concentration of acetic acid, heating temperature, and heating time were set as influential factors, and the yields of chemical compounds were the response values which were optimally designed by a Box-Behnken design. The amounts of 11-keto-β-boswellic acid (KBA) and α-boswellic acid (αBA) in B. carteri resin were quantified using high-performance liquid chromatography analysis. Results Maximum amounts of KBA and αBA in B. carteri resin were obtained using 6% acetic acid for 10 min at 90°C in preliminary test. Two factor interactions, such as acetic acid concentration-heating temperature and heating temperature-heating time, were significantly observed by multiple regression analysis. Optimal processing conditions from RSM were 5.83% for acetic acid concentration, 9.56 min for heating time, and 89.87°C for heating temperature. Under the modified conditions, the experimental value of the response was 11.25 mg/g, which was similar to the predicted value. Conclusions The results suggest that the optimal conditions for the stir-baking process of B. carteri resin were determined by RSM, which was reliable and applicable to practical processing of herbal medicine. SUMMARY The resin of Boswellia carteri was macerated in aqueous acetic acid and heated using an oven for stir baking processThe interaction between heating temperature and heating time was the most significantOptimal conditions for processing B. carteri resin were determined as 5.83% acetic acid, 9.56 min for heating time, and 89.87°C for heating temperature.

Abstract
Pain treatment is still ineffective in many conditions and remains one of the greatest challenges of modern medicine. Historically, due to the incredible variety of pharmacologically promising natural products (NPs) and the chemical complexity of their compounds, scientists have explored their use as a source of treatment for diseases or symptomatology. Fos protein and its precursor, the gene c-Fos, have been the subject of study in relation to the pathophysiology of pain as a possible tool to aid in its understanding. More recently, it has become a useful tool in the study of NPs with analgesic profile. Thus, this systematic review aimed to investigate the analgesic effect of NPs and derivatives through changes in Fos protein or c-Fos expression in nervous system central. The search terms "analgesics," "Fos," and "drug effects" were used in the databases PubMed, MEDLINE, Scopus, and Embase. Forty-six articles were identified. Twenty-five articles investigated Fos expression in the spinal cord, 1 in dorsal root ganglion, 11 in brain areas, and 9 investigated the association between the spinal cord and brain areas. Although Fos protein expression has been used as a tool in the studies of the mechanism of action of pain in relation to NPs with analgesic activity, the associations between brain areas and the spinal cord-and the possible pathways involved-have not yet been fully elucidated and deserve further study.

Abstract
Boswellic acids, which are pentacyclic triterpenes belong to the active pharmacological compounds of the oleogum resin of different Boswellia species. In the resin, more than 12 different boswellic acids have been identified but only KBA and AKBA received significant pharmacological interest. Biological Activity: In an extract of the resin of Boswellia species multiple factors are responsible for the final outcome of a therapeutic effect, be it synergistic or antagonistic. Moreover, the anti-inflammatory actions of BAs are caused by different mechanisms of action. They include inhibition of leukotriene synthesis and to a less extend prostaglandin synthesis. Furthermore inhibition of the complement system at the level of conversion of C3 into C3a and C3b. A major target of BAs is the immune system. Here, BEs as well as BAs including KBA and AKBA, have been shown to decrease production of proinflammatory cytokines including IL-1, IL-2, IL-6, IFN-γ and TNF-α which finally are directed to destroy tissues such as cartilage, insulin producing cells, bronchial, intestinal and other tissues. NFĸB is considered to be the target of AKBA. The complex actions of BEs and BAs in inflamed areas may be completed by some effects that are localized behind the inflammatory process as such tissue destruction. In this case, in vitro- and animal studies have shown that BAs and BEs suppress proteolytic activity of cathepsin G, human leucocyte elastase, formation of oxygen radicals and lysosomal enzymes. PHARMACOKINETICS Whereas KBA is absorbed reaching blood levels being close to in vitro IC50, AKBA which is more active in in vitro studies than KBA, but undergoes much less absorption than KBA. However, absorption of both is increased more than twice when taken together with a high-fat meal.Clinical Studies There are a variety of chronic inflammatory diseases which respond to treatment with extracts from the resin of Boswellia species. Though, the number of cases is small in related clinical studies, their results are convincing and supported by the preclinical data. These studies include rheumatoid arthritis, osteoarthritis, chronic colitis, ulcerative colitis, collagenous colitis, Crohn's disease and bronchial asthma. It can not be expected that there is cure from these diseases but at least improvement of symptoms in about 60-70 % of the cases. Side Effects The number and severity of side effects is extremely low. The most reported complaints are gastrointestinal symptoms. Allergic reactions are rare. And most authors report, that treatment with BEs is well tolerated and the registered side effects in BE- and placebo groups are similar.

Abstract
Cancer pain management is a challenge for which Chinese herbal medicine might be useful. To study the spinal mechanisms of the Chinese medicated gel Long-Teng-Tong-Luo (LTTL), a 7-herb compound, on bone cancer pain, a bone cancer pain model was made by inoculating the tibias of female rats with Walker 256 cells. LTTL gel or inert gel, 0.5 g/cm(2)/d, was applied to the skin of tumor-bearing tibias for 21 days beginning a day after the inoculation. Mechanical threshold and paw withdrawal latency to thermal stimulation was measured. Transient receptor potential (TRP) cation channels in lumbar dorsal root ganglia (DRG) were immunostained and counted, and lumbar spinal cord interleukin-17A (IL-17A) was measured with real-time polymerase chain reaction and enzyme-linked immunosorbent assay. TRP antagonists and interleukin (IL)-17A antibodies were intrathecally administered to determine their effects on bone cancer pain. The gel significantly (P < .05) alleviated cancer-induced mechanical allodynia and thermal hyperalgesia and inhibited cancer-enhanced expression of IL-17A in spinal astrocytes and the TRP subfamily members V1, A1, and V4 in lumbar DRG. Intrathecal TRP antagonists at 10 µg significantly (P < .05) attenuated mechanical allodynia, thermal hyperalgesia, and IL-17A expression, indicating that TRP channels facilitate spinal IL-17 expression and cancer pain. IL-17A antibodies inhibited cancer pain, suggesting that IL-17A promotes such pain. The data show that LTTL gel inhibits cancer pain, and this might be accounted for by the decrease in expression of DRG TRP channels and spinal astrocyte IL-17A.

Abstract
Huo Luo Xiao Ling Dan (HLXLD), a Chinese herbal formula composed of 11 different herbs, has been used traditionally for the treatment of arthritis and other chronic inflammatory diseases. However, the pharmacokinetic profile of its anti-inflammatory bioactive compounds has not been elucidated. Boswellic acids are the bioactive compounds with potent anti-inflammatory activity isolated from Boswellia serrate which is one of the 11 herbs of HLXLD. The objective of the study was to compare the pharmacokinetics of the two bioactive bowsellic acids: 11-keto-β-boswellic acid and 3-O-acetyl-11-keto-β-boswellic following oral administration of HLXLD or Boswellia serrata extract alone in normal and arthritic rats. An LC-MS method was developed and validated for the determination of 11-keto-β-boswellic acid and 3-O-acetyl-11-keto-β-boswellic in the comparative pharmacokinetic study. The results showed that there were significant differences in pharmacokinetic parameters between normal and arthritic groups. Interestingly, the absorptions of two boswellic acids were significantly higher in HLXLD than Boswellia serrata extract alone, indicating the synergistic effect of other herbal ingredients in HLXLD. This comparative pharmacokinetic study provided direct evidence supporting the notion that the efficacy of a complex mixture such as HLXLD is better than that of single components in treating human diseases.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The herbal analgesic gel Tong-Luo-San-Jie (TLSJ) and its modifications are used in traditional Chinese medicine to manage cancer pain. However, its mechanisms are still unknown. AIM OF THE STUDY To investigate the effects and mechanisms of TLSJ gel on bone cancer pain in a rat model. MATERIALS AND METHODS A bone cancer pain rat model was established by inoculating Walker 256 rat carcinoma cells directly into the right tibial medullary cavity of Sprague-Dawley rats (150-170 g); Phosphate buffered saline (PBS) tibial inoculation was used as control. Cancer-bearing rats were treated twice a day with external TLSJ gel (0.5 g/cm(2)/day) or inert gel control for 21 day (n=10/group). Behavioral tests such as mechanical threshold and paw withdrawal latency (PWL) were carried out. Osteoclastic activities were determined and carboxyterminal pyridinoline cross-linked type I collagen telopeptides (ICTP) and bone-specific alkaline phosphatase (BAP) concentrations were detected with ELISA after treatment. Adverse effects were monitored, and biochemical and histological tests were performed in naïve rats treated with local TLSJ gel for six weeks. RESULTS TLSJ treatment significantly restored bone cancer-induced decrease of PWL and mechanical threshold compared to inert gel. It also decreased the level of blood serum ICTP and BAP and inhibited osteoclast activities. No adverse effects or abnormal biochemical and histological changes were detected after TLSJ treatment. CONCLUSION The present study shows that TLSJ significantly inhibits bone cancer-induced thermal and mechanical sensitization. It suggests that the gel may be useful in managing cancer pain and that it may act by inhibiting osteoclastic activity.

Abstract
OBJECTIVE To investigate the safety of oral administration of Modified Huo Luo Xiao Ling Dan (HLXLD), a compound traditional Chinese herbal medicine. METHODS The toxicological information of HLXLD and its individual constituent herbs was searched in cintcm or TCMlars (www.cintcm.com), PubMed (MEDLINE), Chinese Herbal Medicine (1999) and WHO Monographs on Selected Medicinal Plants (Vol. I- III). Single-dose acute toxicity was assessed by using the highest possible dosage. Motor function test was used to determine whether the herbal formula might cause motor impairment. Nine-day HLXLD repeat-dose sub-chronic toxicity/adverse effects, and 42-day chronic toxicity/adverse effects in rats were also assessed. RESULTS The literature searches showed that HLXLD and its eleven ingredient herbs had no side/adverse effects listed in the traditional Chinese medicine literature. Under the dosages proposed in the formula, the HLXLD formula had no side/adverse effects according to MEDLINE, Chinese Herbal Medicine and WHO Monographs on Selected Medicinal Plants. The studies in rats showed: (1) in single-dose acute toxicity assessment, the maximal feasible single oral dose, 9.20 g/kg HLXLD, showed no significant effect on clinical signs, or body weight and mortality over a 14-day period in rats; (2) during motor function test, nine-day repeat-dose of daily HLXLD treatment at 4.60 g/kg did not cause motor impairment; (3) in nine-day HLXLD repeat-dose sub-chronic toxicity/adverse effects assessment, there were no noticeable abnormal behavioral changes or obvious adverse reactions and signs in complete Freund's adjuvant inflamed rats (highest observed dosage: 4.60 g/kg), and no noticeable adverse effects were observed during, or 14 days after nine-day treatment at 4.60 g/kg in non-inflamed rats; (4) during 42-day chronic toxicity/adverse effects assessments, no noticeable abnormal behavioral changes, no obvious adverse reactions and signs were observed in normal rats administered with HLXLD at a dose of 2.30 g/kg and the values of serum biochemistry and histopathology were in normal range. CONCLUSION Both existing information and animal data support that Modified HLXLD is a safe herbal product for clinical application.

Abstract
Irritable bowel syndrome (IBS) is a functional gut disorder with high prevalence. Because of various factors involved in its pathophysiology and disappointing results from conventional IBS medications, the treatment of IBS is challenging and use of complementary and alternative medicines especially herbal therapies is increasing. In this paper, electronic databases including PubMed, Scopus, and Cochrane library were searched to obtain any in vitro, in vivo or human studies evaluating single or compound herbal preparations in the management of IBS. One in vitro, 3 in vivo and 23 human studies were included and systematically reviewed. The majority of studies are about essential oil of Menta piperita as a single preparation and STW 5 as a compound preparation. Some evaluated herbs such as Curcuma xanthorriza and Fumaria officinalis did not demonstrate any benefits in IBS. However, it seems there are many other herbal preparations such as those proposed in traditional medicine of different countries that could be studied and investigated for their efficacy in management of IBS.

Abstract
Non-steroidal anti-inflammatory drug (NSAID) intake is associated with high prevalence of gastrointestinal or cardiovascular adverse effects. All efforts to develop NSAIDs that spare the gastrointestinal tract and the cardiovasculature are still far from achieving a breakthrough. In the last two decades, preparations of the gum resin of Boswellia serrata (a traditional ayurvedic medicine) and of other Boswellia species have experienced increasing popularity in Western countries. Animal studies and pilot clinical trials support the potential of B. serrata gum resin extract (BSE) for the treatment of a variety of inflammatory diseases like inflammatory bowel disease, rheumatoid arthritis, osteoarthritis and asthma. Moreover, in 2002 the European Medicines Agency classified BSE as an 'orphan drug' for the treatment of peritumoral brain oedema. Compared to NSAIDs, it is expected that the administration of BSE is associated with better tolerability, which needs to be confirmed in further clinical trials. Until recently, the pharmacological effects of BSE were mainly attributed to suppression of leukotriene formation via inhibition of 5-lipoxygenase (5-LO) by two boswellic acids, 11-keto-β-boswellic acid (KBA) and acetyl-11-keto-β-boswellic acid (AKBA). These two boswellic acids have also been chosen in the monograph of Indian frankincense in European Pharmacopoiea 6.0 as markers to ensure the quality of the air-dried gum resin exudate of B. serrata. Furthermore, several dietary supplements advertise the enriched content of KBA and AKBA. However, boswellic acids failed to inhibit leukotriene formation in human whole blood, and pharmacokinetic data revealed very low concentrations of AKBA and KBA in plasma, being far below the effective concentrations for bioactivity in vitro. Moreover, permeability studies suggest poor absorption of AKBA following oral administration. In view of these results, the previously assumed mode of action - that is, 5-LO inhibition - is questionable. On the other hand, 100-fold higher plasma concentrations have been determined for β-boswellic acid, which inhibits microsomal prostaglandin E synthase-1 and the serine protease cathepsin G. Thus, these two enzymes might be reasonable molecular targets related to the anti-inflammatory properties of BSE. In view of the results of clinical trials and the experimental data from in vitro studies of BSE, and the available pharmacokinetic and metabolic data on boswellic acids, this review presents different perspectives and gives a differentiated insight into the possible mechanisms of action of BSE in humans. It underlines BSE as a promising alternative to NSAIDs, which warrants investigation in further pharmacological studies and clinical trials.

Abstract
The etiology of inflammatory bowel disease (IBD) is not yet known, but many factors such as defects in the immune system, oxidative stress, microbial content in the gastrointestinal tract, nuclear factor (NF)-κB, nitric oxide (NO), cyclooxygenase-2 (Cox-2), and leukotriene B4 (LB4) are thought to play a role in its pathogenesis. In traditional Iranian medicine (TIM), several medicinal plants are thought to be effective for the treatment of IBD. In this study, information on all of these remedies were derived from all available old sources such as documents or notes and books and were added to the information derived from modern medical databases covering all in vitro, in vivo and clinical trials. For some of these plants, only one or two mechanisms of action have been found such as in Cassia fistula, Lepidium sativum, and Bunium persicum. However, for some plants various mechanisms of action are known. For example, Commiphora mukul is effective in IBD due to its immunomodulatory, antioxidant, and antibacterial properties and it decreases NF-κB, NO and Cox-2. Another herb, Plantago ovata, has immunomodulatory, antioxidant, anti-inflammatory and wound healing activities and decreases NO and LB4. Considering the mechanisms of action of these plants, the combination of some of them may be useful because of their many mechanisms of action such as Pistacia lentiscus, Bunium persicum, Solanum nigrum, Plantago ovata, Boswellia, Solanum nigrum, Plantago ovata and Commiphora mukul. For some of the herbal products used in TIM such as oleogum resin from Commiphora myrrha, seeds of Ocimum basilicum, seeds of Linum usitatissimum, gum resin of Dracaena cinnabari, seeds of Plantago major, seeds of Lallementia royleana, and seeds of Allium porrum, there is no or not enough studies to confirm their benefits in IBD. It is suggested that an evaluation of the effects of these plants on different aspects of IBD should be performed.

Abstract
Chinese herbal medicine has been used for thousands of years in China and other Asian countries to treat a variety of inflammatory diseases. The classic Chinese herbal formula, Huo Luo Xiao Ling Dan (HLXL) is commonly used in traditional Chinese herbal medicine for the treatment of joint pain and other symptoms of arthritis. The present study is an investigation of the effects of a modified HLXL extract on persistent hyperalgesia and edema in rats with peripheral inflammation. Inflammation was induced by injecting complete Freund's adjuvant (CFA) into one hind paw. Four dosages of the extract were compared to a vehicle control. Each was administered intragastrally (i.g.) daily for seven days beginning one day before CFA. Hyperalgesia was assessed using a paw withdrawal latency (PWL) test and edema was determined by measuring paw thickness at pre-CFA and 2 hours, 24 hours, and 5 days post-CFA. Immunohistochemistry was performed 2 hours post-CFA to determine spinal Fos protein expression. Adverse effects of the extract were monitored by observing the animals closely for unusual behavioral changes. Compared to the control, HLXL at the two lower dosages (0.575 g/kg and 1.15 g/kg) were effective in the later stage (day 5) of inflammatory hyperalgesia and edema, while the two higher dosages (2.3 g/kg and 4.6 g/kg) alleviated early stage hind paw inflammation and hyperalgesia and facilitated recovery from paw edema and hyperalgesia during the late stage. HLXL at 2.30 g/kg significantly suppressed Fos expression in laminae I-II, III-IV and V-VI ipsilaterally and in III-IV contralaterally. No significant signs of toxicity or adverse effects were observed. The data suggest that HLXL dosage-dependently attenuates CFA-induced inflammation and hyperalgesia, at least in part by inhibiting noxious transmission at the dorsal horn of the spinal cord.

Abstract
Abstract
Objectives
Despite its historical-religious, cultural and medical importance, Boswellia has not been thoroughly studied, and gaps still exist between our knowledge of the traditional uses of the resin and the scientific data available. Here we review the pharmacology of Boswellia resin and of the small molecules identified as the active ingredients of the resin.
Key findings
The resin of Boswellia species (‘frankincense’, ‘olibanum’) has been used as incense in religious and cultural ceremonies since the beginning of written history. Its medicinal properties are also widely recognized, mainly in the treatment of inflammatory conditions, as well as in some cancerous diseases, wound healing and for its antimicrobial activity. Until recently, work on Boswellia focused on the immunomodulatory properties of the resin and boswellic acids were considered to be the main, if not the only, active ingredients of the resin. Hence, this family of triterpenoids was investigated by numerous groups, both in vitro and in vivo. These compounds were shown to exert significant anti-inflammatory and pro-apoptotic activity in many assays: in vitro, in vivo and in clinical trials. We recently found incensole acetate and its derivatives, which are major components of Boswellia resin, to be nuclear factor-κB inhibitors, thus suggesting that they are, at least in part, responsible for its anti-inflammatory effects. Incensole acetate also exerts a robust neuroprotective effect after brain trauma in mice. Furthermore, it causes behavioural as well as anti-depressive and anxiolytic effects in mice. It is also a potent agonist of the transient receptor potential (TRP)V3 channel. It thus seems that incensole acetate and its derivatives play a significant role in the effects that Boswellia resin exerts on biological systems.
Conclusions
Altogether, studies on Boswellia resin have provided an arsenal of bio-active small molecules with a considerable therapeutic potential that is far from being utilized.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE HLXL is a traditional Chinese medicine that has long been used in folk medicine for the treatment of chronic inflammatory diseases. However, the precise immunological mechanisms by which HLXL mediates its anti-inflammatory activity are not fully defined. AIM OF THE STUDY To determine the effects of HLXL on antigen-specific immune parameters in adjuvant-induced inflammation model in the Lewis rat. MATERIALS AND METHODS Rats were fed daily with either HLXL (2.3g/kg) or vehicle (water) beginning 3 days before subcutaneous injection of heat-killed Mycobacterium tuberculosis H37Ra (Mtb), and then continued for another 6 days. After 9 days of Mtb injection, the draining lymph node cells were tested for T cell proliferative and cytokine responses against mycobacterial heat-shock protein 65 (Bhsp65). Moreover, sera were tested for anti-Bhsp65 antibodies and nitric oxide (NO). RESULTS HLXL-treated rats showed reduced T cell proliferative response to Bhsp65 compared to control rats. Furthermore, HLXL suppressed IL-17 response but enhanced IL-10 response without much effect on IFN-gamma. HLXL treatment also reduced the levels of anti-Bhsp65 antibodies but not that of NO. CONCLUSIONS HLXL feeding modulated both the cellular and the humoral immune response to Bhsp65 favoring an anti-inflammatory milieu for the suppression of adjuvant-induced inflammation.

Abstract
This review, containing over 276 references, covers the progress made in the chemistry and bioactivity of this important group of triterpenoids. Though initially known for their anti-inflammatory and anti-arthritic activities through a unique 5-LO inhibition mechanism, boswellic acids have recently attained significance due to their anti-cancer properties. The phytochemistry and chemical modifications, including mechanism of action, are discussed.

Abstract
Herbal drugs constitute a major share of all the officially recognised systems of health in India viz. Ayurveda, Yoga, Unani, Siddha, Homeopathy and Naturopathy, except Allopathy. More than 70% of India's 1.1 billion population still use these non-allopathic systems of medicine. Currently, there is no separate category of herbal drugs or dietary supplements, as per the Indian Drugs Act. However, there is a vast experiential-evidence base for many of the natural drugs. This offers immense opportunities for Observational Therapeutics and Reverse Pharmacology. Evidence-based herbals are widely used in the diverse systems and manufactured, as per the pharmacopoeial guidelines, by a well-organised industry. Significant basic and clinical research has been carried out on the medicinal plants and their formulations, with the state-of-the-art methods in a number of Institutes/Universities. There are some good examples. Indian medicinal plants also provide a rich source for antioxidants that are known to prevent/delay different diseased states. The antioxidant protection is observed at different levels. The medicinal plants also contain other beneficial compounds like ingredients for functional foods. Hence, the global knowledge about Ayurveda and Indian herbals will hopefully be enhanced by information on the evidence-base of these plants. This will yield rich dividends in the coming years.

Abstract
Ruxiang (Gummi olibanum), the dried gum resin of Boswellia carterii (BC), has been used in traditional Chinese medicine to alleviate pain and inflammation for thousands of years. In this random, blinded study, the anti-arthritic effects of a BC extract were observed and compared to vehicle control in a Lewis rat adjuvant arthritis model (n=8/group). Arthritis was induced by injecting CFA subcutaneously into the base of the tail, and the extract was administered orally (i.g.) for 10 consecutive days beginning on day 16 after the injection. Arthritic scores, paw edema, and the local tissue pro-inflammatory cytokines tumor necrosis factor alpha (TNF-alpha) and interleukin-1 beta (IL-1beta) were assessed. Toxicity and adverse effects of the extract were evaluated. At 0.90 g/kg per day, BC significantly decreased arthritic scores between days 20 and 25 (p<0.05) and reduced paw edema on days 18, 20 and 22 compared to control (p<0.05). It also significantly suppressed local tissue TNF-alpha and IL-1beta (p<0.05). No major adverse effects were observed in animals during the repeated-dose treatment profile although mild fur discoloration was noted. The data show that BC extract has significant anti-arthritic and anti-inflammation effects and suggest that these effects may be mediated via the suppression of pro-inflammatory cytokines.
