It was a pleasant surprise to meet Jonathan, a Massai who took interest in caring for his teeth. After I told Jonathan I was a Doctoriae Wa Meno-- (Dentist), we visited the Pepper Plant. He broke off a branch and we stripped the bark from the limb. "This is a Massai toothbrush. Scrub your teeth and you will taste the pepper."
I'll admit the Pepper Plant toothbrush had a winter-fresh flavor similar to Colgate. Jonathan worked his toothbrush for the next 30 minutes.
