Hello, the effect of applying Chinese medicine to navel to lose weight actually depends on your own situation. The operation of applying traditional Chinese medicine to navel is very simple: after the navel is cleaned, lie flat, take a proper amount of prepared powder, mix it with ginger juice or yellow wine, honey and vinegar, put it in the navel hole, cover it with gauze and fix it with breathable tape. Generally, 6- 12 hours are reserved. Skin sensitive person can shorten the time, and those with good skin tolerance can extend it appropriately, but it is best not to exceed 24 hours, and generally lasts for 2-7 days. People with acute pathological changes, damp heat in the body, navel inflammation or severe skin allergy should not be treated with this method. In addition, it is not advisable to apply Chinese medicine to the navel immediately after an empty stomach or meal.
