A large shrub whose bark is very strong medicinally and used for killing several species of fungus, candida, staphylococcus, herpes and tumors. Bark must be at least two years old or it’s too strong. Careful! Do not confuse with the very toxic cherry laurel (Prunus caroliniana) which also has blue-black fruit, but the leaves are simpler cherry leaves.
