What's the function of vinegar soaked coix seed?

Coix lachryma-jobi extract must be added to all major skin care products, because it has obvious effects of lightening spots, whitening and reducing swelling. Coix seed is slightly cold and does not hurt the stomach, and it is beneficial to the spleen and not greasy. In severe cases, the dose can be increased. For pregnant women, people with insufficient body fluid and nocturnal emission, they should take it in moderation, not in large quantities.

Coix seed is preferably white particles, and powder will reduce the efficacy. Can be decocted alone, or taken together with sesame, milk and mung bean.
