What are the health benefits of barley water?

Barley water is good for flushing the kidneys

My dad has an enlarged prostate. While researching for other natural remedies, it also said barley water is good to drink if you have an enlarged prostate. Is barley water something I should also introduce to my father to help with his prostate?

My mother suffers from frequent uti's. We have been researching natural ways to help prevent and ease them so that she is not on so many antibiotics and ran across barley water as a natural remedy. Is this something she should try? Does it actually help?

I have been looking for a natural remedy to improve my blood pressure and came across barley water as being good for the heart and blood pressure. Is this something I should add to my diet? Also, is barley water okay to drink when you are pregnant? Thank you!

Hi @lekenne, welcome to Mayo Clinic Connect. You'll notice that I moved your questions about barley water into one discussion that appears in multiple related groups. My go to resource for inquiring about complementary medicine and supplements is the National Center for Complementary and Integrative Health (NCCIH) https://nccih.nih.gov/ They do not have any evidence-based information about barley water. I found this article however:
- Health Benefits of Barley Water https://www.healthline.com/health/barley-water-benefits

There is some evidence that barley water might help with lowering cholesteral, controlling blood sugar, losing weight, improves digestion and may help reduce the risk of cancer. There are also some cautions about drinking too much and to check if it has added sugar or sweetner. Too much can put a strain on your digestive system.

@sickirishlass, the article didn't mention anything about barley water being used to flush the kidneys. Do you have articles about its use for kidney health?
@lekenne, if you're pregnant, I recommend talking to your doctor before taking any supplement or barley water.
