Notes:
Saleem et al. (2022) found that a 20% methanolic extract of Convolvulus arvensis improved wound healing in mice.
Although Todd et al. (1995) found low levels of topane alkaloids in C. arvensis that could explain intestinal fibrosis in horses that are chronically exposed, however Khaliq et al. (2022) found no alkaloids in neither ethyl acetate or methanol extracts so acute toxicity from tropane alkaloids is probably low.

Reference Notes:
Individual herb information has sourced mainly from TCM Wiki and American Dragon for basic data and then updated manually with my own notes. Zhou, Xie and Yan (2011): Encyclopedia of Traditional Chinese Medicines, Vol. 5, and A+ Medical Encyclopaedia have been used for entries not available from those sources with additional material searched for and filled in where available. Western herbs not appearing in the Chinese literature have used Ross (2010): Combining Western Herbs and Chinese Medicine: A Clinical Materia Medica, White Rabbit Institute of Healing and therapeutika.ch. Choices of which source to use or combine have been my own.
These pages are intended to assist clinicians and are not intended for self-diagnosis or treatment for which a qualified professional should be consulted.

Dosages are for guidance only and will vary dependening on the potency of the batch and the tolerance of the individual so should be evaluated by a professional based on individual needs.
