Historical Properties & Uses
Southernwood has been largely overshadowed by its famous relative, wormwood. It possesses many of the same properties as wormwood, but is considered safer. Southernwood is a cholagogue, useful in the treatment of digestive disturbances.
Method of Action
Southernwood has been found to have good choleretic activity. In one study on rats, southernwood was found to be the best choleretic among those tested.
Animals in the alcohol control group experienced no increase in bile secretion or solids excretion. Those given an alcoholic extract of southernwood brought about a 60% increase in bile secretion and a 50% increase in solids. The active principle was tentatively identified as isofraxidin which is comparable to dehydrocholic acid in intensity.
Drug Interactions & Precautions
Southernwood should be used with caution in conjunction with CNS depressants or stimulants.
The topical application of this astringent herb, in conjunction with the acne product tretinoin (retinoic acid, vitamin A acid), may adversely affect the skin.
In the absence of other hard data, it may still be assumed observable interactions may occur between the many central nervous system drugs and the psychoactive principles in southernwood.
