Shen Ling Baizhu Powder is mainly used for treating damp diarrhea. Although it is said that it is due to spleen deficiency, it actually treats both the symptoms and root causes (spleen-invigorating drugs are few and heavy, while moisture-absorbing and antidiarrheal drugs are many and light). Even if it's spleen deficiency, you don't have to eat if you don't see loose stool.

Xiang Jun attached importance to Atractylodes macrocephala and Poria cocos, focusing on eliminating dampness. Generally, the dampness is heavier than spleen deficiency, and the medicine is peaceful.

Fragrant sand, Cyperus rotundus and Fructus Aurantii Immaturus, warm and dry cardamom and Magnolia Officinalis have the effects of invigorating spleen and eliminating dampness, and are warm in nature.

Therefore, the fragrant sand is flat, and the fragrant sand for nourishing the stomach is warm. LZ is effective in nourishing the stomach, but it is ineffective because it is stomach cold (LZ complains of chills).

You can take it all the time, but it is best to take it half an hour to an hour before meals.
