Auricularia auricula can dissolve and melt foreign bodies such as indigestible hair, chaff, wood residue, sand and metal chips. In order to prevent and treat gastrointestinal discomfort or diseases caused by various foreign bodies, it is advisable to eat some black fungus frequently, especially those engaged in hairdressing, mining, dust, sawing, repairing and road protection.

Auricularia auricula also has a significant dissolving function on endogenous foreign bodies such as gallstones, kidney calculi, bladder stones and fecal stones. The fermentation and plant alkaloids contained in Auricularia auricula have the characteristics of promoting the secretion of various glands in digestive tract and urinary tract, and cooperate with these secretions to catalyze stones, lubricate pipes and discharge stones.

At the same time, Auricularia auricula also contains a variety of minerals, which can produce a strong chemical reaction to various stones, peel off, differentiate and erode stones, so that stones can be shrunk and discharged. For initial stones, taking auricularia auricula for 1~2 times a day can relieve the symptoms such as pain and nausea in 2~4 days, and the stones can disappear in about 10 days. For larger and stronger stones, the effect is poor, but if you eat auricularia auricula for a long time, some people's stones will gradually become smaller and broken and be excreted. Eating black fungus often can also prevent thrombosis and other diseases.
