There is no clear evidence that drinking cornhusk every day can improve kidney function.
Cornhusk is a water-inducing and dampness-expelling (promoting the flow of water to dispel dampness) type of traditional Chinese medicine, with a sweet taste and calm nature, it can enter the bladder meridian, liver meridian and gallbladder meridian, drinking cornhusk water has the effect of inducing diuresis to reduce oedema, and diuresis to dispel dampness and jaundice (removing dampness to dispel jaundice).
It is suitable for patients with edema and jaundice. However, the dose of drinking cornhusk water is limited, generally does not play a role in treating diseases, and has no obvious effect on improving kidney function.
People who are allergic to cornhusk should avoid using it, and patients with dry mouth and tongue and other fluid injuries should use it with caution. Adverse reactions are not yet clear. Do not eat spicy and greasy food during the medication.
Patients with renal insufficiency need to decide whether to take cornhusk water under the guidance of a professional Chinese medicine practitioner who can identify the evidence, and it is not recommended to drink it blindly, and they should go to the hospital for consultation and treatment in time to avoid delaying their condition.
