Homeopathic solutions for chronic dry mouth include eating a mixture of aniseed and fennel seeds as well as drinking cardamom water, according to HomeVeda. One teaspoon of aniseed should be mixed together with one teaspoon of fennel seeds prior to eating. This mixture improves bad breath and saliva flow.
For a second method, add a teaspoon of cardamom powder into a glass of hot water, mix it properly and let the concoction stand for 15 minutes prior to drinking. As with the aniseed and fennel mixture, doing this daily gets rid of bad breath and moisturizes the mouth.
Additionally, keeping the body hydrated by drinking lots of water and eating fruits, lessening the intake of carbonated drinks and staying away from tobacco or cigarettes, can also help.
