Kegan Liyan oral liquid (KGLY), a Chinese prescription modified from classic formulas Yin-Qiao-San (from TCM classic Wenbing Tiaobian) and Shen-Jie-San (first mentioned in Shanghan Wenyi Tiaobian), has been reported to exert heat-clearing and detoxifying effects and used extensively for the treatment of severe pulmonary diseases in clinics including influenza, cough and pneumonia. ⋯ The results suggested that the relieving effect of KGLY against LPS-induced ALI might be partially due to suppression of oxidative stress and inflammatory response, inhibition of TLR4-mediated NF-κB activation, and down-regulation of MMP9 expression, indicating it may be a potential therapeutic agent for ALI.

Petiveria alliacea L. commonly grows in the tropical regions of the Americas such as the Amazon forest, Central America, Caribbean islands and Mexico, as well as specific regions of Africa. Popularly known by several different names including 'mucuracaá', 'guiné' and 'pipi', P. alliacea has been used in traditional medicine for the treatment of various central nervous system (CNS) disorders, such as anxiety, pain, memory deficits and seizures, as well as for its anaesthetic and sedative properties. Furthermore, the use of this species for religious ceremonies has been reported since the era of slavery in the Americas. Therefore, the present review aims to provide a critical and comprehensive overview of the ethnobotany, phytochemistry and pharmacological properties of P. alliacea, focusing on CNS pharmacological effects, in order to identify scientific lacunae and to open new perspectives for future research. ⋯ Many traditional uses of P. alliacea have now been validated by modern pharmacology research. The available data reviewed here support the emergence of P. alliacea as a potential source for the treatment of different CNS disorders including anxiety, depression, pain, epilepsy and memory impairments. However, further studies are certainly required to improve the knowledge about the mechanisms of action, toxicity and efficacy of the plant as well as about its bioactive compounds before it can be approved in terms of its safety for therapeutic applications.

Randomized Controlled Trial Multicenter Study Comparative Study
Prospective, randomized, double-blinded, double-dummy and multicenter phase IV clinical study comparing the efficacy and safety of PG201 (Layla) and SKI306X in patients with osteoarthritis.
This prospective, randomized, double-blinded, double-dummy, multicenter study compared the efficacy and safety of PG201 (Layla®), a new product from extracts of 12 plant sources and SKI306X (Joins®) which have been well investigated and in relatively wide usage among herbal medicine, for the treatment of patients with knee osteoarthritis. ⋯ The results of this study showed that PG201 significantly reduced knee pain and improved knee function and were comparable to SKI306X. PG201 can be suggested as an effective treatment of knee osteoarthritis. Trial registration ClinicalTrials.gov:NCT01768468.

The genus Litsea is one of the most diverse genera of evergreen trees or shrubs belong to Lauraceae, and comprises roughly 400 species of tree that are distributed abundantly throughout tropical and subtropical Asia, North and South America. Litsea species have been used globally in traditional medicine for the treatment of various diseases including influenza, stomach aches, diarrhea, diabetes, vomiting, bone pain, inflammation, illness related to the central nervous system and other ailments. The purpose of this review is to provide updated, comprehensive and categorized information on the ethnobotany, phytochemistry and pharmacological research of Litsea species in order to explore their therapeutic potential and evaluate future research opportunities. ⋯ From data collected in this review, the genus Litsea comprises a wide range of therapeutically promising and valuable plants, and has attracted much attention owing to its multiple functions. Many traditional uses of Litsea species have now been validated by modern pharmacology research. Deep and systematic phytochemical investigation of the genus Litsea and the pharmacological properties, especially its mechanism of action and toxicology, to illustrate its ethnomedicinal use, explore the therapeutic potential and support further health-care product development will undoubtedly be the focus of further research. Therefore, detailed and extensive studies and clinical evaluation of Litsea species should be carried out in future for the safety approval of therapeutic applications.

Review
Traditional uses, phytochemistry and pharmacological properties of Neolamarckia cadamba: A review.
There are more than 3000 officially documented plants in the Indian subcontinent that hold great medicinal potential. One such under-explored plant is an evergreen tropical tree Neolamarckia cadamba (Roxb.) Bosser (Rubiaceae). It is widely distributed in tropical and subtropical regions of the world and has therapeutic potential against many diseases such as diabetes, anaemia, stomatitis, leprosy, cancer and infectious diseases. Neolamarckia cadamba has historical existence in India and it is mentioned in mythical stories. There are several reports on medicinal values of root, bark and leaves of N. cadamba; but the literature on its fruits is scanty. Therefore, the present review aims to provide updated comprehensive information on the phytochemistry and pharmacological properties of different parts of N. cadamba tree with special reference to its fruit, in order to open new perspectives for future food and pharmacological research. ⋯ The present review compiles information on an ethnopharmacologically useful plant N. cadamba. Bioactive compounds responsible for its various medicinal properties and their effects at the molecular level need to be investigated in more detail. Furthermore, the detailed study of toxicity and pharmacological properties of extracts as well as molecules in N. cadamba is required to confirm the ethnomedicinal claims of N. cadamba for food and pharmaceutical applications.
