While you can take this tonic mixed into warm water, take this straight for best results and to feel that clearing feeling.
This is an original Malcolm Harker tonic. Malcolm recommended:
taking this tonic straight, or added to 50ml of boiled water as a tea
avoiding mucus forming foods such as gluten, egg-white, chocolate, dairy, polyunsaturated oils and regular table salt
adopting gluten-free grain foods, whole foods (greens, fruits nuts, seeds), unprocessed coconut oil and Celtic & NZ Sea Salt with Kelp
With all his tonics, Malcolm also recommended using Intestinal Cleanse for 1-2 weeks to reduce parasite populations. By reducing the load on the body of parasites, the body is able to use nutrients from food and the active ingredients in his tonics more efficiently.
