Ahungalla is a great place to learn about Ayurveda, an ancient Sri Lankan form of medicine that utilizes natural remedies and ingredients to heal most injuries and afflictions. Once you're at a Spice Garden you'll be shown around by someone who studies the subject. They will take you around all of the plants, pointing out all their many healing qualities. They'll also explain how the plants are used today in Sri Lanka as well. You'll be able to see many herbs and spices like the original Ceylon cinnamon, cardamom, ginger, and lemongrass. At the end of the tour, you'll be taken to a small shop that sells all the different lotions and medicine that was explained to you if you're interested in purchasing any.
