Can Lycopodium be steeped in water for drinking?

Generally speaking, Herba Lycopodii (Qian Ceng Ta) can be consumed as a tea, but excessive intake should be avoided. A detailed explanation is as follows:

Herba Lycopodii is a traditional Chinese herb that primarily affects the liver, spleen, and kidney meridians. It has functions of dispelling wind-dampness and promoting blood circulation to relieve stiffness and pain. This herb has a mild nature, with a bitter and slightly pungent taste. Drinking Herba Lycopodii tea typically provides health benefits, and individuals experiencing symptoms such as joint aches and limited mobility may find some relief by consuming it in moderation.

However, excessive consumption may cause accumulation of its warm nature in the body, transforming into heat pathogens and leading to symptoms of excessive internal heat, such as dry mouth, sore throat, and constipation. Individuals with a naturally hot constitution or those already suffering from internal heat conditions are more prone to these adverse reactions. Therefore, it is recommended to consume Herba Lycopodii in moderation. Additionally, special populations such as pregnant women, nursing mothers, women during menstruation, and children should avoid consuming Herba Lycopodii tea to prevent potential adverse effects.

While consuming Herba Lycopodii tea, it is advisable to maintain a bland diet and avoid spicy or stimulating foods, as these may interfere with the herb's effectiveness.
