Mamaki (Pipturus albidus) is a native herb to Hawaii and has been considered a sacred plant for generations. It is also called Hawaiian Nettle and is said to be the only nettle plant that does not have stinging leaves. It is said that local Hawaiians give the tea to the sick and the weak, and that this tea helps regulate high blood pressure and diabetes. This caffeine-free, anti-oxidant rich herbal tisane contains catechins, chlorogenic acid, and rutin. The tea becomes a deeper red the longer it steeps.
