Generally speaking, the effects and benefits of red bean and coix seed water mainly include promoting diuresis and reducing edema, strengthening the spleen and eliminating dampness, providing nutrients, enhancing metabolism, and relieving fatigue. The details are as follows:

1. Promoting Diuresis and Reducing Edema

Both red beans and coix seeds have diuretic properties. When boiled into a beverage, they help the body expel excess water, alleviate mild edema in the limbs, and improve conditions such as difficult urination. When the body has excessive dampness or mild swelling, drinking this water can help reduce swelling and make the body feel lighter.

2. Strengthening the Spleen and Removing Dampness

Coix seeds help strengthen the spleen and drain dampness, while red beans nourish the blood and support spleen function. Together, they enhance the effect of strengthening the spleen, improving symptoms such as poor appetite and physical heaviness caused by spleen deficiency and excessive dampness. For individuals with weak spleen and stomach function or excessive dampness, drinking this water can help regulate the spleen and stomach and eliminate internal dampness.

3. Providing Nutrients

Red bean and coix seed water contains protein, B vitamins, potassium, and other nutrients. Protein is an essential component of body tissues, B vitamins assist in metabolism, and potassium supports heart function. Drinking it in moderation can supply these nutrients and support normal physiological activities of the body.

4. Enhancing Metabolism

The dietary fiber in red beans and coix seeds promotes intestinal motility, helping to eliminate metabolic waste from the intestines. Additionally, their nutrients participate in the body's metabolic processes. Regular consumption can support normal metabolism and reduce the accumulation of waste substances.

5. Relieving Fatigue

The carbohydrates in red bean and coix seed water provide energy to the body, helping to restore physical strength and alleviate fatigue caused by excessive energy consumption. When feeling tired, drinking this beverage can help restore energy and maintain a better physical condition.

Red bean and coix seed water are relatively cooling in nature, so individuals with a cold body constitution should not consume large amounts over a long period, as it may worsen internal coldness. Pregnant women should consume it cautiously to avoid any adverse effects from coix seeds. As a dietary therapy beverage, it cannot replace medical treatment for diseases. If health issues exist, timely medical consultation is necessary. Individuals in special conditions should consult healthcare professionals before consumption.
