Taste is a connecting sense. For example, the taste of food brings pleasure to nourishment, and taste helps to bring our minds close to the foods impacting our health and bodies. Even things you don’t enjoy the taste of such as medicine or even cilantro can be an indicator for health concerns.
The mouth has over a million nerve endings, which is part of why taste is so impactful. Even holistic remedies that are held in the mouth before being ingested are being absorbed in a different way than anything that is simply swallowed, just because of the added element of taste.
