Betel husk is from a palm call betel tree.  The nuts from the tree are often chewed as a stimulant along with the betel leaf.  Betel leaf is not from the same tree but from a vine (Piper Betie) belonging to the Piperaceae family.  The nuts are used by almost 1/10 of the world's population as a stimulant that's equal to 6 cups of coffee.  It's effectiveness can be compared to nicotine, alcohol and caffeine.  Arecoline is the psychoactive constituent that makes betel nuts a heavy stimulant.  This usage leads to oral cancer and prompting governments for regulation.[ref]
