In southern spring, when the humidity is heavy, you should always drink damp herbal tea. Its raw materials are Coicis Semen, Rhizoma Dioscoreae, Poria, Lily, Atractylodis Rhizoma, Flos Chrysanthemi Indici, Radix Rehmanniae, Radix Paeoniae Rubra, Flos Lonicerae, etc. Civil use of kapok and frangipani tea also has a certain dehumidification effect, but kapok must be cleaned before cooking to prevent heavy metal pollution.
