This is the 1oz tincture version of our popular Aged Cascara Sagrada powder.
Cascara Sagrada is known for its natural digestive regularity benefits. Properly aged Cascara is much less harsh than other Cascara products. Cascara sagrada is never to be used fresh and must be aged for at least a year to break down its anthrone chemicals. (The Cascara offered by Health Natura is aged) If the bark is not aged, it is a purgative and will cause intense intestinal spasms and vomiting. The herb can be chemically processed or heating but some useful constituents may be lost and the end product is harsher than naturally aged Cascara. In recent times, it has been used as an ingredient in sunscreen products, as well as a flavoring agent in foods such as candy, frozen dairy desserts, and baked goods.
I originally started carrying this upon the request of several Ray Peat protocol users. We went through several sources and finally settled on this one based on their positive feedback.
