If you have lost your sense of taste and smell due to sinusitis, cayenne pepper is the solution for you. Capsaicin, its active compound, helps in reducing nasal congestion. Saliva production is also stimulated, and this in turn improves taste. A mixture of a teaspoon each of cayenne pepper and honey taken a couple of times every day will help in loosening up mucus and stimulates secretion. Black pepper is also an excellent stimulator for taste buds
You can use a special blend of herbs and bentonite clay to treat loss of taste and smell. Use the mixture in your bath water every day. This has been known to be highly effective in restoring the sense of taste and smell for some people. It is worth a try.
Oil pulling is an ancient Ayurvedic practice that is known to help in treating loss of smell and taste as it moistens your taste buds. It also helps in removing toxins from your mouth and body. You can use sesame oil, coconut oil or other edible oils for oil pulling. Take a tablespoon of your preferred oil and swish it around your mouth thoroughly for about 15 minutes. Rinse your mouth with warm water after spitting the oil out. Do this daily in the morning before you eat anything.
