Nisim International develops and manufactures all of the products it sells from a facility northwest of Toronto, Canada. Nisim has developed a proprietary system for extracting the active ingredients from the herbs used in all of its products. This system allows us to get the maximum effective strength from the herbs. We are so confident of our products that we back them with an unconditional 100% money back guarantee. Many people ask us the origin of our name - Nisim actually means "Miracle" in hebrew (the original owners of the company created the name).
