Description: Olive trees are tough. The secret of their long life under harsh conditions is Oleuropein. This plant makes this substance to resist diseases and pests. The leaves of Manzanillo and Mission Olive Trees contain unusually high amounts of Oleuropein and other substances that could be of benefit to humans.
Olive Leaf is a natural herbal antibiotic and antioxidant that can support the body's ability to fight or prevent many diseases. The active compounds of Oleuropein and Eleonic Acid in Olive leaf have been reported to act as an Antimicrobial agent, which slows invaders enough for the body's natural immune system to react. The result is a natural antibiotic and antioxidant with effects similar to garlic and onions. Olive leaf can be enjoyed regularly as a preventative or used directly to combat ailments. In turn, oleuropein itself consists of elenolic acid and calcium elenolate, which work synergistically to repel a wide spectrum of microorganisms. Contains no additives or preservatives.

Appearances: Fine Green or Brownish yellow Powder
