Root of Roughhaired Holly Classic Formulas … Natural Herb Library

Primary Actions

Clears heat and resolves toxicity ... Gang Mei is a southern Chinese root used for febrile congestion, heat-toxic throat swelling, and inflammatory upper-respiratory patterns.
Benefits the throat and relieves painful swelling ... it is particularly associated with sore throat, swollen tonsils, and the hot congested feeling treated by herbal tea and cold-relief traditions.
Cools inflammatory irritation without being the same herb as Mao Dong Qing ... it belongs to the holly-root family but follows a more throat and fever oriented lane.

Gan Mao Ling type cold-relief traditions ... Gang Mei is one of the well-known southern heat-clearing roots used when fever, throat pain, and upper-respiratory congestion travel together.
Throat-swelling pairings with Ban Lan Gen, Jin Yin Hua, or Xuan Shen ... common logic when toxicity and redness dominate.
Heat-clearing herbal tea combinations ... Gang Mei is often included when a cooling bitter-sweet root is wanted without strong purgation.

Southern Chinese usage consistently places Gang Mei among herbs that clear heat, resolve toxicity, and relieve throat discomfort.
Its medicinal identity is regional and practical, but it has enough market presence to deserve clear separation from other Ilex roots.
