Indian Long Pepper Overview
Indian long pepper, also known as pippali or pipali, is a plant species native to India and other parts of South and Southeast Asia. It is a member of the Piperaceae family. The fruit of the plant, which has a pungent, slightly sweet flavor, is harvested and dried for use as a spice.
Indian long pepper has also been used in Ayurvedic medicine to treat a variety of ailments, including digestive problems, pain, poor blood circulation, respiratory disorders, and fever. One of the constituents of Indian long pepper is piperine, which can have wide ranging effects, including increasing the bioavailability (i.e., rate and extent of absorption) of several different drugs. It is often combined with over-the-counter supplements, like turmeric, to increase their absorption.
