Hello. Chinese patent medicines for invigorating spleen and eliminating dampness include Guipi Pill, Muxiang Shunqi Pill, Jianpi Pill and Shen Ling Baizhu Powder. Each kind has similarities in invigorating spleen and eliminating dampness, but the actual medication should be differentiated according to the theory of syndrome differentiation of traditional Chinese medicine.
If you can't tell which medicine is right for you, I suggest you describe the symptoms clearly and let the doctor help you choose.
