The main ingredient of wind oil essence is menthol, which has the effect of cooling, dispersing wind and dispersing evil, and the effect of treating diarrhea is not too obvious. If the diarrhea is of the damp-heat type, the use of wind essential oil applied around the navel may provide some relief, but the effect is not particularly obvious either. It is best to treat it with other heat-clearing and anti-diarrhea medicines, such as Scutellaria baicalensis and Pueraria lobata soup, Enterococcus granulosus, and Simethicone and other medicines. If it is dyspeptic diarrhea, the treatment should not have much efficacy. For dyspeptic diarrhea, it can be treated with stomach-strengthening and eliminating herbs, such as oral Baohe Pills and Ginseng Ling Baijusan. You should also eat less cold, spicy and stimulating foods, drink more water, eat more light meals and avoid catching cold.
