Although houttuynia cordata can be used as medicine or edible, it is not suitable for some special people. Clinical medical research shows that it is not recommended to eat more in these three situations!
1. Deficiency of spleen and stomach: Houttuynia cordata Thunb is a cold substance, so it can clear away heat and toxic materials, and is suitable for patients with heat stranguria, carbuncle, swelling and sores.

In recent years, medical research shows that the extract of Houttuynia cordata Thunb also has a certain anti-cancer effect. In the famous magazine Cancer, Nagoya City University of Japan published a research result. This study showed that Houttuynia cordata extract and its ethyl acetate component (EA) could activate caspase, down-regulate androgen receptor and inactivate AKT/ERK/MAPK signal transduction, and promote androgen-sensitive prostate cancer cells (LNCaP) and CRPC cells (PCAI 65438+).
Of course, the anti-cancer effect of Houttuynia cordata Thunb extract is still in the animal experimental stage. Scientists mixed Houttuynia cordata extract with EA to make animal feed, and then fed the prepared feed to experimental mice. It was found that mice that ate this feed had a lower risk of prostate cancer than mice that didn't eat it. In other words, the extract of Houttuynia cordata Thunb does have a certain inhibitory effect on cancer cells. Scientists said that although houttuynia cordata extract has not been widely used in clinical anti-cancer, this research is of great value in the future human anti-cancer road. # Healthy Summer # # Healthy Star Project #
