As a Ying-Spring point, SP2 is known for clearing heat from the Spleen meridian and resolving dampness, making it effective for acute Spleen-related conditions. It is particularly useful for damp-heat manifesting as loose stools, diarrhea, or dysentery, as well as for heat in the Spleen presenting with fever, thirst, or a red tongue. It also strengthens the Spleen's function of transformation and transportation, benefiting digestion. It can be combined with SP3 for a stronger effect on Spleen deficiency with dampness.
