Clinical Perspective
Xiang Ru Yin releases exterior summer-damp with cold signs. Huo Xiang Zheng Qi San more broadly resolves damp turbidity for gastrointestinal summer disorders. Liu Yi San clears summer-heat and drains damp without exterior release. Qing Shu Yi Qi Tang tonifies Qi while clearing summer-heat for deficiency presentations.
