Human noses have 10,000 scents they can pick up on. While that's not near as many as dogs have, it's still a lot. The nose is powerful, able to sniff essential oil and command the body to perform as the properties of the oils dictate. But what is it about a nose that makes it about to smell?

Human noses have 10,000 scents they can pick up on. While that's not near as many as dogs have,
The nose has tons of receptors in it - like 400 of them. Furthermore, it protrudes from one's face so it can catch sniffs. Everything about the nose is set up to succeed as far as scents and smells go. It takes a scent and sends it to the brain and the brain makes to decision of what to do with the scent. Sometimes it reminds us of something good or something bad. Sometimes, as in the case of essential oils, it tells the body to relax or to heal. The nose is an amazing thing. The 400 sensories that are packed in it are loaded with abilities to make the scent something good, like a rose, or something bad...like poop. Somehow, someway, the nose and its components all make scents.
