What are the side effects and toxicity of Ligustrum fruit?

Ligustrum fruit, as a traditional Chinese medicinal herb, has many benefits such as nourishing the liver and kidneys, improving vision, and darkening hair. However, it also has certain side effects and precautions that should be noted during use. 1. Side effects: Ligustrum fruit may cause mild gastrointestinal symptoms such as dry mouth, abdominal pain, and diarrhea, especially when taken long-term, in large doses, or without medical supervision. Ligustrum fruit has a certain laxative effect; therefore, patients who already have diarrhea may experience worsening symptoms even with the usual dosage. 2. Toxicity: Ligustrum fruit itself does not exhibit obvious toxicity. However, due to its relatively cold nature, it is not advisable for patients with deficiency-cold of the spleen and stomach or kidney-yang deficiency to take large amounts of this single herb alone, as it may exacerbate their condition. Although Ligustrum fruit offers many health benefits, it is not suitable for everyone. It should be used appropriately according to individual constitution and under a physician's guidance to avoid possible side effects and adverse reactions.
