Dr. John Christopher’s Immune Tonic has been my staple DIY immune boosting supplement for years. This tonic is designed to raise your internal temperature to boost your immune system. I can’t remember a winter in which I got sick when I was taking this tonic daily.

Here’s a secret you need to know: Herbs and natural remedies work best when taken at the first sign of illness. Herbs can stop sickness in its tracks if taken soon enough and at the right potency. So eat these foods, mix these remedies, take these herbs and Stay Well!
