Health Beyond Danger: Ancient Longevity & Tonic Herbs with Master Herbalist Rehmannia D. Thomas

From the very beginning of COCORAU, our mission has been anchored in true functional wellness, not just masking symptoms, but feeding the body at a cellular level. That’s why we have collaborated with Rehmannia D. Thomas since day one to formulate our elite elixir lines.

Rehmannia is a Master Taoist Tonic Herbalist in a 5,000-year-old lineage known as the Gate of Life. He is one of only two herbalists in America to hold an official title in this ancient tradition. Rather than focusing on acute sickness, his work centers on Tonic Herbs: a superior class of adaptogenic, perennial plants and mushrooms (like Reishi and Chaga) that are safe for long-term consumption and explicitly designed for cellular protection, preventative health, and systemic balance.

We sat down with Rehmannia to discuss the history of his lineage, how true adaptogens work, and what it means to achieve what the ancient masters called "health beyond danger."

The Origin Story: From Musician to Master Apprentice

Konstanze: What inspired you to do what you do?

Rehmannia: As a youngster, everything about China fascinated me... Then when I first found out about Chinese culture, I'd get these shivers, you know, and then I met a Chinese woman. And when I was 21 years old, I was in a rock and roll band, and I met a Chinese woman, and she did my astrology, and she told me that I had been a Chinese doctor in a past life. And I started going like this, "Oh..

And so we wound up getting married, and we went to China on our honeymoon in 1985... One night, we were staying in a town in northern China called Jilin, which is where the herbs are collected and brought to that town as the main hub in the northern Manchurian province of China. And by the way, this place is very clean. Most of it is now a U.N. biosphere. It's got a geography similar to Vermont and New Hampshire. It's a very clean place. This is where our herbs come from, just so people know this right away because there's a lot of propaganda about Chinese herbs being tainted...

So we came back to America, and she said, "Let's make some Chinese herbal tinctures." ... We found a book called "Chinese Tonic Herbs" by a man named Ron Teeguarden. This was in the year 1986... Fast-forward to the year 1998, I had been doing some healing work as a green juicing therapist working with people who were really sick... and I wanted to learn a deeper thing. I actually prayed one morning for a teacher to teach me something.

Well, that very night... they said, "Now folks, for your pleasure and enjoyment, master herbalist Ron Teeguarden is here to speak with you." ... I went up to him afterward and said, "Sir, I'm a fan. My wife and I have your book." He looked at me. He goes, "Come tomorrow." So he gave me his address, and I came over to his place the next morning... I made this tea that takes like three hours... I took it up to him three hours later, and he cut off the little tip of the rhetoric pouch, poured it in his cup, and took a sip and went, "Mm." He goes, "You're my tea master."

So I became his tea master... I became Ron Teeguarden's personal apprentice for eight years. And he taught me the precepts of the Gate of Life lineage, which is the lineage of Taoist tonic herbalism... It wasn't about sickness yet. It was about prevention and wellness and empowerment and longevity.

The Power of Prevention: Why Tonic Herbs Matter Now

Konstanze: What makes you the most happy about the work you do?

Rehmannia: Well, the same reason. It's just a wonderful feeling to know that you really did. Someone in college said, "My God. I really do feel better." And we've always believed in natural medicines, you know, natural medicines are real medicine and the new medicine is the alternative medicine..

But when it comes to the tonic herbs, I think when we get a balance in society, they will embrace the tonic herbs. I don't know how much investment they would like to put into prevention. That's the whole thing. But the tonic herbs can help prevent us from getting sick. The tonic herbs are very important in the diet of all people on earth now because when combined with a living food diet, you must eat well. You cannot take tonic herbs on their own and expect to have complete health

You must eat local, fresh, organic, and go to your farmer's place... So now, you do those things, and you take tonic herbal elixirs. Actually, I give myself credit, it was my innovation to come up with bulk powder extract in a jar that you add into your drink, and you make it... Because what the tonic herbs do is they're supplying deeper nutrients. They're more complex. So they're called polysaccharides, polyphenols, ganoderic acids, and these kinds of things that are deeper and they're embedded in that herb because the herbs are perennial plants... They survive the cooking process, and actually, it activates their bioavailability for us.

Navigating the Modern World: Tuning the Genome

In a world full of daily environmental stressors, heavy chemical loads, and metabolic fatigue, Rehmannia explains why the cellular intelligence of plants is our best defense mechanism for longevity.

Rehmannia: The tonic herbs help take the nutrients deeper into replenish our kidneys, replenish our adrenals, regulate our immune response and regulate stress response to help modulate and regulate metabolism. And the tonic herbs have a way of helping us have a very peaceful spirit, as you know about reishi mushroom, the great reishi.

We can attain what the ancient masters called health beyond danger. And they were the so-called immortals of ancient Chinese lore... Even with the toxins of our world, and here's why the tonic herbs are unveiling themselves to us at this time because the toxins of the world have come to a place where we are imperiling our lives.

The genome, every cell in our body, is actually an antenna to a vast mind... and that master gardener sends us messages through every cell, those cells involved in our evolution as a species... All of these are messages that are given. And those messages are unveiled, based on our vitality... So when we take the tonic herbs, we're tonifying the energies of the organs to balance them. That's our job. Then the job is to eat right, live right, get some sunlight, get some minerals, and drink good water. Get up in the morning and drink a glass of pure water with nothing in it. No lemon, no nothing. First thing in the morning, hydrate your body. Drink some saltwater before bed. Balance the forces, and we can overcome the onslaught of the toxins and the stress that we face right now... This is the tonic herbs showing up now after 5,000 years have been hidden in the mountains of China.

Konstanze: Thank you, Rehmannia.

Rehmannia: All right. Thank you, Konstanze.
