Can normal people eat Cornus officinalis (Shanzhuyu)?

Generally speaking, healthy individuals can consume Cornus officinalis (Shanzhuyu), but it should be taken under the guidance of a professional traditional Chinese medicine practitioner to ensure its effectiveness and safety. The detailed analysis is as follows:

As a traditional Chinese medicinal herb, Cornus officinalis has functions of nourishing the liver and kidneys, consolidating essence, reducing urination, and stopping perspiration. Healthy individuals can take it in appropriate amounts under a doctor's guidance. It can also be used as an ingredient in daily cooking, such as in soups or porridge, providing certain health benefits. However, those who have a history of allergy to Cornus officinalis or other related plant components should avoid consumption to prevent allergic reactions.

Furthermore, Cornus officinalis is slightly warm in nature with a sour and astringent taste. Excessive consumption may lead to discomfort. Healthy individuals with a constitution leaning towards excessive internal heat, symptoms such as dry mouth and throat, sore throat, or constipation, or those showing signs of damp-heat in the body, generally should avoid consuming Cornus officinalis to prevent aggravating internal heat or damp-heat conditions and triggering or worsening symptoms.

It is recommended to purchase Cornus officinalis from reputable sources to ensure quality and safety. Before consumption, consult a doctor or TCM practitioner for advice on whether it is suitable for you, as well as on the appropriate dosage and method of use.
