Phytotherapy Research is a monthly, international journal for the publication of original research papers, short communications, reviews and letters on medicinal plant research. Key areas of interest are pharmacology, toxicology, and the clinical applications of herbs and natural products in medicine, from case histories to full clinical trials, including studies of herb-drug interactions and other aspects of the safety of herbal medicines. Papers concerned with the effects of common food ingredients and standardised plant extracts, including commercial products, are particularly welcome, as are mechanistic studies on isolated natural products.

Short communications dealing with the pharmacology and screening of crude or uncharacterised extracts will be considered for publication only if they are clearly of interest to our international readership and are not deemed more suitable for a regional audience.

Phytotherapy Research does not publish agricultural, phytochemical, structure elucidation, quality control or botanical identification papers unless directly pertinent to the pharmacological effects or overall safety of plant based medicines currently in use.
