Patients with hepatitis B do not usually experience any adverse reactions when eating Colla Corii Asini. However, it is possible that eating too much of this tonic may nourish the stomach and lead to gastrointestinal indigestion and abdominal distension. If you eat less or with spleen-healthy drugs, such as Shen Qu, malt, chicken naijin, etc., you can reduce the possibility of adverse reactions in this regard. If you take Agaricus blazei, it will not be greasy and obstructive to the stomach. For hepatitis B patients, this state of hepatitis B virus infection in the body is not aggravated by the consumption of Agaricus blazei. However, it does not usually make this condition particularly significantly better, so it is not a contraindication or an indication for people with hepatitis B to take Colla Corii Asini. Whether or not a person should take Colla Corii Asini depends on whether or not the person has a Yin or Blood deficiency condition. If there is any of these conditions, taking Colla Corii Asini is a more appropriate choice. If there is no yin deficiency or blood deficiency, it is not necessary to take Colla Corii Asini.
