Is there any side effect of Chi Shao (Red Peony Root) on the liver and kidney?

Generally speaking, whether Chishao (Radix Paeoniae Rubra) has side effects on the liver and kidney depends on specific circumstances. If used correctly as directed by a physician, it typically does not cause side effects. However, long-term and excessive use may lead to adverse effects. Detailed analysis is as follows:

Chishao is a commonly used traditional Chinese herb that has functions of clearing heat, cooling blood, dispersing blood stasis, and relieving pain. When taken under the guidance of a physician or pharmacist according to the prescribed dosage and duration, it generally does not cause significant side effects to the liver and kidney. When used appropriately, Chishao can exert effects such as cooling blood and promoting blood circulation without imposing a burden on the liver and kidney.

Long-term and excessive use of Chishao may negatively affect liver and kidney function. Because Chishao has a cold nature, prolonged use may lead to deficiency-cold of the spleen and stomach, thereby affecting liver and kidney function. Additionally, high-dose usage of Chishao may increase the burden on the liver, leading to abnormal liver function and even drug-induced liver injury.

When using Chishao, it is important to follow a physician's guidance, adjusting the dosage and duration based on individual constitution and medical condition. Maintaining healthy lifestyle habits, such as moderate exercise and a balanced diet during treatment, along with regular monitoring of liver and kidney function, can help maintain overall health.
