Medicinal Uses & Benefits of Alder Buckthorn

remedyHow to Use| Side Effects | Plant & Garden|

How to Use:

The dried and aged bark is the part used in herbal medicine, primarily as a laxative. Frangula bark is considered to be milder in action than aloes and senna with only minimal irritant properties, about the same as rhubarb. It is a close relative of the California buckthorn, Cascara sagrada The slightly gentler action makes it more suitable to those with chronic constipation as a tonic to re-educate the bowel. For persistent cases frangula with not suffice on its own and is often combined with carminatives and stronger laxatives.(Weiss, Rudolf Fritz M.D.)

Preparation Methods & Dosage :Tablets, tea and tinctures

Side Effects: If the buckthorn is not aged, it is not laxative, it is purgative, causing intense intestinal spasms and vomiting. As with all laxative herbs it is not meant for continuous long term use.
