In Traditional Healing, male partners of newly wed couple are given special Paan as gift in which many types of herbal roots are added. This Paan acts as powerful Aphrodisiac. They are suggested to keep this Paan in mouth and let the juice of fresh roots go inside the stomach. The Healers claim that till this process continues "nothing" comes out from body. Makra root is one of these roots.
