Is raw Cornus officinalis toxic? Can it be consumed?

Raw Cornus officinalis (Shanzhuyu) is generally non-toxic, but it is not recommended for direct consumption.

As a traditional Chinese medicinal herb, raw Cornus officinalis itself is non-toxic. When used appropriately and in proper dosages, it can be taken as medicine for nourishing the liver and kidneys, consolidating essence and reducing urinary frequency, stopping leukorrhea, and stabilizing pregnancy. It is commonly used to treat symptoms such as soreness and weakness of the waist and knees and dizziness and tinnitus caused by yin deficiency of the liver and kidneys. It may also help improve conditions like nocturnal emission and spermatorrhea. Under the guidance of a TCM physician, moderate use of raw Cornus officinalis is considered safe.

Although Cornus officinalis is non-toxic, direct consumption may cause some side effects. Some individuals may experience gastrointestinal discomfort, such as nausea, vomiting, abdominal pain, or diarrhea. Additionally, Cornus officinalis may trigger allergic reactions, such as rashes or itching. The dosage of herbal medicines must be strictly controlled according to individual conditions and specific illnesses. Direct consumption of Cornus officinalis makes it difficult to accurately determine the appropriate dosage, and excessive intake may have adverse effects on the body.

In daily diets, unless there is a specific need and under the guidance of professionals, it is not recommended to arbitrarily add or consume large amounts of raw Cornus officinalis.
