Cerez Pazari 25g Reselable Bag Natural Real Chios Mastiha (Mastic Gum) Medium Tears Chios mastiha (or mastic) is the natural resin that oozes from the trunk and branches of the mastic tree, merging like tear drops. This sticky, thick fluid hardens after about 15 days into irregular crystals of varying shapes and sizes. Since ancient times, mastiha, exclusively found on the Greek island of Chios, has been renowned for its medicinal and therapeutic values and as an exotic spice. It is also often referred to as the oldest superfood in the world. The health benefits of mastiha were initially discovered by Hippocrates and first recorded by Dioscorides, a first century pharmacologist as he described the positive effects the resin could have on ones health.
