In terms of content structure, this article will introduce the traditional applications, modern pharmacological research, applicable groups and precautions of M. ganglenum in order to help readers fully understand its value and usage specifications.
Traditional applications and folk experience

In the Lingnan area, Gangmei has long been used to relieve fever, such as summer heat or wind-heat colds. Folks often slice it into water or decoct it to improve throat discomfort and dry mouth. It is cool in nature and slightly bitter in taste, and it belongs to the lung and stomach meridians. It is especially suitable for people with damp-heat constitution. According to the "Lingnan Medicine Collection Record", the compatibility of Megonia root with honeysuckle and mint can enhance the effect of clearing away heat and detoxifying, which reflects the traditional wisdom of compatibility.

Summary and reasonable use suggestions
Gangmei has both traditional value and modern scientific verification, and is a practical medicinal material for treating fever.
