Kauai Grown

For thousands of years, healers have turned to Comfrey — the original "knit-bone" — to mend what modern medicine struggles to reach. The Comfrey Cast is our most concentrated Comfrey formula: pure Kauai-grown Comfrey root, solar-dehydrated at low temperatures to preserve live enzymes, then ground into a potent healing powder.

Mix it with water, apply it to the body, and let it work. It's that simple — and that powerful.

What It Supports

  • Broken & fractured bones
  • Sprains, strains & torn ligaments
  • Swelling, bruising & inflammation
  • Joint pain, arthritis & carpal tunnel
  • Hernias, bulging discs & rotator cuff injuries
  • Dental & gum discomfort (topical application)

Why Comfrey Root

The root holds a significantly higher concentration of allantoin — Comfrey's key cell-regenerating compound — than the leaves. Our root is harvested on our Kauai farm, slow-dried in a solar dehydrator to lock in live enzymes, and ground fresh to preserve full potency.

How to Apply

  1. Measure enough powder to cover the affected area
  2. Add water gradually and mix into a paste (thickness depends on injury size and type)
  3. Apply immediately after mixing — it must be wet to adhere properly
  4. Let air dry completely; it will set from a flexible fruit-leather texture to a firm cast depending on thickness
  5. Leave on as long as possible for best results
  6. To remove: let dry pieces crumble off, then loosen the rest with lukewarm water

⚠️ For topical use only. Do not ingest. Comfrey Cast is not an edible product and should never be made into a tea or consumed internally.

Frequently asked

Questions & answers

Is comfrey safe for topical use?

Yes. Topical comfrey applied to intact skin is well-tolerated and has been the subject of numerous clinical trials. We recommend external use only and avoid open wounds — see below.

How is your comfrey grown and harvested?

Biodynamically, on our Kauai farm. Grown without chemicals; pests are managed with healthy soil and companion planting. Harvested by hand, dried slowly, and processed on-site.

How long until I feel results?

Varies by condition. Many customers report relief within days for muscle / joint issues; deeper bone or tendon work tends to need 2–6 weeks of consistent use.

Is it pregnancy / nursing safe?

Consult your healthcare provider. We don't make claims here — comfrey's pyrrolizidine alkaloid content is a topic to raise with someone who knows your specific situation.
