What Are the Side Effects of Consuming Red Ginseng?

Red ginseng is an expensive tonic herb renowned for its potent qi-tonifying effects. For individuals with weak constitutions, it can effectively enhance immune function. However, caution must be exercised when consuming red ginseng to avoid potential adverse effects, as it may stimulate the nervous system and intensify conditioned reflexes—potentially leading to hypoglycemia or hypotension.

What Are the Side Effects of Red Ginseng?

Red ginseng exerts a stimulatory effect on the nervous system. After ingestion, users may experience insomnia, weight loss, or depressive symptoms; therefore, timing and dosage must be carefully considered. Accidental overdose may result in hypotension, skeletal muscle paralysis, or respiratory paralysis. Consequently, strict dose control is essential during administration. Excessive intake can cause marked hypoglycemia and suppress myocardial contractility—effects resembling those of cardiac glycosides—and may lead to hypotension, respiratory paralysis, and skeletal muscle paralysis. Thus, ginseng use must adhere to sound therapeutic principles: pattern differentiation (syndrome identification), appropriate indication-based prescribing, clear distinction between deficiency and excess patterns, and avoidance of indiscriminate or excessive use.

Red ginseng is warm in nature and may disrupt the normal yin-yang balance in healthy individuals, exacerbating yang-heat, thereby inducing “excess heat” symptoms such as dry mouth, oral ulcers, and epistaxis. These manifestations are particularly pronounced during hot summer weather. Fortunately, discontinuing use promptly typically leads to resolution of these symptoms. Individuals with deficient constitutions may require long-term red ginseng supplementation.
