Cold and dampness in the body: Pueraria powder is a cold food. People with cold body and dampness will aggravate the accumulation of coldness in the body after eating it, which can easily cause physical discomfort.
Hypotension: Since the puerarin contained in kudzu root powder can unclog blood vessels and lower blood pressure, patients with hypotension are not suitable for eating kudzu root powder.
Hypoglycemia: This is also due to puerarin. Since it can lower blood pressure and blood sugar at the same time, patients with hypoglycemia should not consume pueraria powder.
