Shungite is a powerful natural stone known for protecting against Emf fields and geopathic stress due to its unique molecules, Fullerenes. Wearing shungite bracelets can positively affect various body systems—cardiovascular, digestive, nervous, respiratory, and immune—by interacting with bioactive spots on the wrist. On the left wrist, shungite improves blood flow, reduces stress, and enhances brain function. On the right wrist, it boosts brain energy and stamina. Wearing shungite on both wrists creates a continuous energy circuit, strengthening the body. Shungite also promotes cell growth and brain function, helping the body relax. The bracelet may leave black stains, this is due to the high amount of carbon in shungite composition. If you have the issue, please wash your bracelet carefully under running warm water to get rid of micro dust, which leaves those stains. After you washed it several times, the amount of residue will diminish.
