Sorbi aucupariae fructus, mountain ash berry.
Mountain ash berry consists of the fresh or dried fruit, or fruit cooked and dried thereafter, of Sorbus aucuparia L. s.l. [Fam. Rosaceae], as well as preparations thereof.
Mountain ash berry and its preparations are used for kidney diseases, for diabetes, arthritis, disorders of the uric acid metabolism, for dissolution of uric acid deposits, for catarrh, internal inflammations, vitamin C deficiency, for alkalization of the blood, increase of metabolism, and for "blood purification."
The effectiveness of the claimed applications is not verified.
Note: Fresh mountain ash berry contains parasorbic acid, which causes local irritation. During the drying process, the compound is largely degraded. It is fully destroyed upon cooking.
Since the effectiveness of mountain ash berry for the claimed applications is not documented, a therapeutic use cannot be recommended.
