Can clover rhizomes be eaten?

Clover, also known as oxalis, is generally edible in its rhizome form, but should be consumed in moderation. The detailed analysis is as follows:

Oxalis rhizome is a traditional Chinese medicinal herb with sour and cold properties, affecting the liver and lung meridians. It contains substances such as oxalate, malic acid, and citric acid, giving it significant medicinal value. It can clear heat and dampness, cool the blood to detoxify, and dissipate blood stasis and swelling. Decoctions made from oxalis rhizome can be used to treat conditions such as fever due to colds, urinary tract infections, enteritis, urinary stones, and neurasthenia. Therefore, moderate consumption of oxalis rhizome benefits health.

However, oxalis rhizome contains high levels of acidic substances, and excessive consumption may cause gastrointestinal discomfort. Additionally, due to its cold nature, individuals with cold body constitution, excessive stomach acid, and pregnant women should avoid consuming it. People allergic to oxalis rhizome must not consume it.

As an herbal medicine, oxalis rhizome should be consumed without spicy or irritating foods to avoid interfering with its therapeutic effects.
