Herbal tea made from dianthus orchids often appears in my house. The cooking method is very simple, just a few pouch orchid leaves, plus some plantain or three or two pandan leaves. Cook for an hour and add some rock sugar. The purple tea is very beautiful, there is no special herbal flavor, with a faint pandan leaf scent, it is filled with three or two cups under the heat, and the whole body is immediately relieved.
