Abstract
Obesity is a worldwide public health problem whose prevalence rate has increased steadily over the last few years. Therefore, it is urgent to improve the management of obesity and its comorbidities, and plant-based treatments are receiving increasing attention worldwide. In this regard, the present study aimed to investigate a well-characterized extract of Lavandula multifida (LME) in an experimental model of obesity in mice and explore the underlying mechanisms. Interestingly, the daily administration of LME reduced weight gain as well as improved insulin sensitivity and glucose tolerance. Additionally, LME ameliorated the inflammatory state in both liver and adipose tissue by decreasing the expression of various proinflammatory mediators (Il-6, Tnf-α, Il-1β, Jnk-1, Pparα, Pparγ, and Ampk) and prevented increased gut permeability by regulating the expression of mucins (Muc-1, Muc-2, and Muc-3) and proteins implicated in epithelial barrier integrity maintenance (Ocln, Tjp1, and Tff-3). In addition, LME showed the ability to reduce oxidative stress by inhibiting nitrite production on macrophages and lipid peroxidation. These results suggest that LME may represent a promising complementary approach for the management of obesity and its comorbidities.

Abstract
Forest trees are the world's most important renewable natural resources in terms of their dominance among other biomasses and the diversity of molecules that they produce. Forest tree extractives include terpenes and polyphenols, widely recognized for their biological activity. These molecules are found in forest by-products, such as bark, buds, leaves, and knots, commonly ignored in forestry decisions. The present literature review focuses on in vitro experimental bioactivity from the phytochemicals of Myrianthus arboreus, Acer rubrum, and Picea mariana forest resources and by-products with potential for further nutraceutical, cosmeceutical, and pharmaceutical development. Although these forest extracts function as antioxidants in vitro and may act on signaling pathways involved in diabetes, psoriasis, inflammation, and skin aging, much still remains to be investigated before using them as therapeutic candidates, cosmetics, or functional foods. Traditional forest management systems focused on wood must evolve towards a holistic approach, allowing the use of these extractives for developing new value-added products.

Aqueous extract of Paeoniae Radix Alba (Paeonia lactiflora Pall.) ameliorates DSS-induced colitis in mice by tunning the intestinal physical barrier, immune responses, and microbiota. J Ethnopharmacol 2022; 294:115365.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ulcerative colitis (UC) is a chronic non-specific intestinal inflammatory disease, the pathogenesis of which is strongly associated with the compromised intestinal barrier. Paeoniae Radix Alba (PRA), the root of Paeonia lactiflora Pall., is a well-known traditional Chinese medicine and an adaptogen used in Hozai, exhibiting appreciable anti-inflammatory and immunomodulatory activity. Nevertheless, the role and mechanism of PRA in UC have yet to be elucidated. AIM OF THE STUDY This study was set out to examine the ameliorative effects of the aqueous extract of PRA (i.e., PRA dispensing granule, PRADG) on dextran sulfate sodium (DSS)-induced colitis. MATERIALS AND METHODS The chemical components of PRADG was analyzed by HPLC. Colitis model mice were induced by free access to water containing 2.5% DSS for 10 consecutive days, and concurrently, PRADG (0.1025 and 0.41 g/kg) or Salazosulfapyridine (SASP, 450 mg/kg) was given orally from day 1-10. Body weight, disease activity index (DAI), colon length, histologic scoring, and inflammatory response were assessed. Additionally, IL-23/IL-17 axis and tight junction (TJ) proteins, as well as gut microbiota were also investigated under the above-mentioned regimen. RESULTS Eight main chemical constituents of CPT were revealed with HPLC analysis. Noticeably, PRADG could effectively lower body weight loss as well as DAI scores, alleviate colon shortening, and reduce the levels of proinflammatory cytokines in mice with colitis. Further exploration found that increment of TJ proteins expression (ZO-1, occludin and claudin-1) and inhibition of IL-23/IL-17 axis-modulated inflammation were observed in PRADG-treated mice. Additionally, the diversity of gut microbiota and the relative abundance of beneficial bacteria were increased following PRADG treatment. CONCLUSIONS PRADG could be sufficient to ameliorate colitis by regulating the intestinal physical barrier, immune responses, and gut microbiota in mice. Our findings highlight that PRADG might be a prospective remedy for UC.
