This topical formula helps support the immune system. This herb comes from the bark of Pau d' Arco trees and has been used by Brazil's indigenous people for centuries. Despite being native to lush tropical forests, this tree has no fungal growth because it contains lapachol. This may which account for the herb’s traditional use in strengthening and supporting the immune system.
