Benefits of Coat Buttons Plant for Health

According to a scientific report based on research written by Yusuf Andriana et al. (2019) said that Tridax procumbens or the coat button plant is a medicinal plant that has been used as a drink to treat catarrh, diarrhea, dysentery and liver disease. In the study, it was found that the coat button plant showed a strong inhibitory effect on XO, antioxidants, and the growth of four strains of bacteria E. coli, P. mirabilis, S. aureus, and B. subtilis. So it can be said that the coat button plant is a promising source for developing drinks and food to treat hyperuricemia, oxidative stress, and bacterial infections.

Traditionally in India, the coat button plant is used as a medicine to cure diabetes, diarrhea, jaundice, inflammation and wound healing and is used as a mosquito repellent, to help check bleeding and treat hair loss (Beck et al., 2018) .
