Among the wide diversity of naturally occurring phenolic acids, at least 30 hydroxy- and polyhydroxybenzoic acids have been reported in the last 10 years to have biological activities. The chemical structures, natural occurrence throughout the plant, algal, bacterial, fungal and animal kingdoms, and recently described bioactivities of these phenolic and polyphenolic acids are reviewed to illustrate their wide distribution, biological and ecological importance, and potential as new leads for the development of pharmaceutical and agricultural products to improve human health and nutrition. © 2010 licensee MDPI Basel Switzerland.

Future research of herbal products for menopausal women should include long-term safety assessments because women may use these products for prolonged periods of time. Growing numbers of women take prescription medications and concurrently use herbal products for alleviation of menopausal symptoms. Because of possible herb-drug interactions, both drug and supplement manufacturers should provide basic pharmacokinetic data to reduce the risk of adverse interactions. In addition, herbal products produced to high quality standards are essential for ensuring consumer safety. Regulatory frameworks must be in place to ensure that herbal ingredients' identities have been verified, that they have been properly quantified per unit dose, that the product is within tolerance limits for contaminants, that the product's safety and effectiveness under the recommended conditions of use have been assessed before sale to the public, and that a system is in place to detect and deal with adverse reactions when they arise. This article explores these and related concerns.

Ethnopharmacological relevance/Introduction In Canada, all natural health products (NHPs) are regulated by Health Canada (HC) under the Food and Drugs Act and the Natural Health Product Regulations. All authorized products undergo pre-market assessment for safety, efficacy and quality and the degree of pre-market oversight varies depending on the risk of the product. Overview In Canada, over 70,000 products have been authorized for sale and over 2000 sites have been licensed to produce NHPs. In the management of NHPs on the Canadian market, HC employs a number of active and collaborative methods to address the most common issues such as contamination, adulteration and deceptive or misleading advertising practices. HC is currently evolving its approaches to NHPs to recognize them as part of the larger group of health products available without a prescription. As such, the regulatory responsibility for all over-the-counter (OTC) drugs, including non-prescription drugs and NHPs, has been transferred to a single federal division. Conclusion As a result of this transition a number of benefits are being realized with respect to government efficiency, clarity for industry, support for new innovations and consolidated government interactions with the Canadian market. © 2014 Elsevier Ireland Ltd.
