Caslan Bio French Lentin du chêne is a mushroom that grows on oak trees. European oak is fine-grained, hard and white, also known as white oak, and is one of the best wood species in the world. Its roots often coexist with the mycelium of Boletus to form a mushroom cluster. The mushrooms that grow are large and strong, with short stalks, thick caps, strong fragrance and delicious taste. It is known as the "Queen of Plants" and is a mushroom that can be used as both medicine and food. It contains a high concentration of active Lentinan, which can clear and benefit the lungs, help fight against haze, and has antitussive and antiasthmatic effects.
 Experts at Kaslan carefully selected high-quality genetic spores from French Nogdan for Bio Living Zhi® French Nogdan Essence Powder, cultivated high-quality mycelium using test tube technology, and precisely cultivated in a pure environment. They repeatedly studied and used advanced organic planting technology using "soilless bottles" and then shipped them to France for organic cultivation. All products have obtained EU and French organic product certification. When the French Nogdan pods mature, Bio Living Zhi® French Nogdan Essence Powder is extracted using high technology to ensure that it contains high concentrations of effective active ingredients, which can bring health benefits if taken for a long time.
