Can Prunella vulgaris be steeped in water for consumption?
Generally speaking, Prunella vulgaris can be consumed as an herbal tea, but it should be taken in moderation. Detailed explanations are as follows:

Prunella vulgaris is cold in nature, with a bitter and pungent taste, and has functions of clearing liver heat, improving vision, dispersing nodules, and reducing swelling. Drinking an appropriate amount of Prunella vulgaris tea can help alleviate symptoms such as excessive liver heat, red and swollen eyes, and swollen lymph nodes. When used correctly and in moderation, Prunella vulgaris tea can be a method of health maintenance.
However, it is important to control the dosage and avoid excessive consumption to prevent potential adverse effects on the body. Long-term and excessive consumption may cause gastrointestinal discomfort, especially for individuals with cold deficiency of the spleen and stomach, who should use it cautiously. Pregnant women, nursing mothers, and children should avoid drinking Prunella vulgaris tea, as its cold nature may have adverse effects on the fetus or infant. Individuals with cold deficiency of the spleen and stomach also should avoid its use to prevent aggravating the condition and causing symptoms such as abdominal pain and diarrhea.
During consumption of Prunella vulgaris, spicy, greasy, and cold foods should be avoided, as they may interfere with recovery. Any adverse reactions should be monitored closely during use. If discomfort occurs, consumption should be stopped immediately and medical advice should be sought.
