Rice water is one of the oldest natural health drinks used across Asia for centuries. Traditionally valued for its nourishing properties, rice water is made by soaking, boiling, or fermenting rice in water and then consuming the nutrient-rich liquid.

Many people drink rice water as a refreshing beverage, while others use it externally for beauty and personal care purposes. Rich in carbohydrates, small amounts of vitamins, minerals, and plant compounds, rice water can be a useful addition to a balanced lifestyle when consumed in moderation.
This guide explores everything you need to know about rice water, including its nutrition facts, science-backed health benefits, side effects, preparation methods, storage tips, and more.
What is Rice Water?
Rice water is the starchy liquid left behind after rice has been soaked, boiled, or fermented in water. During the preparation process, some nutrients from the rice dissolve into the water, creating a mild, cloudy beverage.
Rice water has been used traditionally in countries such as China, Japan, India, and Korea for both dietary and cosmetic purposes. Depending on how it is prepared, rice water may have a slightly sweet, earthy, or fermented flavor.
The three main types of rice water are:
- Soaked rice water
- Boiled rice water
- Fermented rice water
Each type contains varying amounts of nutrients and beneficial compounds.
