1. People with qi deficiency, yang deficiency, and damp-heat constitution are not suitable to take donkey hide gelatin orally.

2. The main reason is that donkey-hide gelatin is relatively greasy in nature and taste. People with qi and yang deficiency constitutions take it orally and it will affect the digestive function. They will not be able to supplement the deficiency, and may cause abdominal distension, nausea, vomiting, and indigestion. There are few cases; people with a damp-heat constitution will aggravate their condition after taking donkey-hide gelatin orally. This is mainly because donkey-hide gelatin has the side effect of promoting dampness, so people with a damp-heat constitution are not suitable to take donkey-hide gelatin.
