Is water bamboo (Zizania latifolia) cold-natured or hot-natured?

Generally speaking, water bamboo (Zizania latifolia) is considered to have a cold property in terms of food attributes. Detailed analysis is as follows:

The cold nature of water bamboo gives it the effects of clearing heat, promoting body fluid production, and diuretic properties that help relieve internal heat and assist in expelling excess water from the body when consumed during hot summer months. Moreover, water bamboo is rich in dietary fiber, which helps stimulate intestinal movement and prevent constipation. It also contains various vitamins and minerals that help maintain normal body metabolism, enhance immunity, and particularly contains potassium, which is beneficial for regulating blood pressure. Additionally, water bamboo has a considerable amount of protein and contains essential amino acids required by the human body.

However, due to its cold nature, individuals with weak spleen and stomach functions or those prone to diarrhea should avoid excessive consumption to prevent additional strain on the gastrointestinal system. Patients suffering from gout or urinary tract stones should also consume it cautiously, as water bamboo contains relatively high levels of oxalic acid, which may affect their conditions. Furthermore, water bamboo should not be consumed in large quantities together with calcium-rich foods such as tofu, to avoid the formation of calcium oxalate, which could increase the risk of stone formation.
