This process of sun-drying for one day followed by fermentation for one day is repeated until fully dry, after which any remaining twigs and stems are sifted out. It has a bitter, slightly sweet taste and a cool nature.It can clear heat and eliminate toxins, relieve summer heat and promote fluid production, and relieve food stagnation and promote diuresis.
