HistoPlex-AB™ supplies a proprietary blend of herbal extracts shown to possess immunomodulating properties. Specific botanical compounds are recognized as effective agents in assisting the body's immune system in coping with the onset on allergy symptoms. Select herbs provide specific actions to support the respiratory system, and in turn may function to modulate the immune system, resulting in a less severe immune reaction.
I have used this product for years. I have sinus issues and this product seems to help a little. Pricing is a issue for me and your price is the best. I will continue to order from you as needed
