Herbal Calcium Formula Recipe – Dr. Christopher’s Calc Tea

Dr. Christopher’s calcium formula is a blend of herbs rich in calcium, silica, and other minerals. This herbal calcium is popular for strengthening bones and remineralizing teeth (healing dental cavities) naturally. This herbal calcium blend tastes really good. It’s not bitter or unpleasant at all.

Herbal Calcium Testimonials

Tooth grows back: “My oldest daughter aged 13 now, had a dental cavity at age 7 (the only dental cavity among our six children). We had the cavity drilled out and a filling put in by our local dentist. Two years later, the filling came out and a hole was left in her tooth. Nothing more was done about it except the herbal calcium formula that you recommend in your book, School of Natural Healing, made up of: comfrey, horsetail, oat straw, and lobelia. This combination of herbs has been used very consistently by the entire family over the last two years. We have recently discovered that the hole where the filling was is now completely grown over and is absolutely unnoticeable even under close inspection.” (source)

    Thank you for sharing these recipes on herbal calcium. I’m fairly new to following Dr. Christopher’s work and I do drink Comfrey infusion often using the leaves. I watched a week long Comfrey Conference on Susun Weed’s Wise Woman School a couple of years ago- very informative as I think we’ve forgotten how valuable this plant is. Also last year the same website offered a St. John’s Wort/St. Joan’s Wort Conference and this year’s focus will be on Red Clover, ahhh the magic of plant medicines for healing🌿🌹🌻
