10. Myrrh Extract
Here is a spice that you probably recognize from the biblical story of the birth of Jesus. That will give you some idea how long people have known that it makes effective medicine.
Much more recently, a 2000 study confirmed that myrrh is able to combat bacteria like E. coli, staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans. Myrrh oil is available today in pharmacies, natural grocers, and online.
