SINCE 1987

Providing TCM clinicians with extraordinary, one of a kind, herbal tea concentrates.

As TCM practitioners, we should

never close the door on change.

Because even just a little more capability in a medicine can make all the difference.

For better results, try using stronger medicine. Not more medicine: more capable medicine.

If we don’t experience new things, we don’t get better.

If a raw herb pharmacy is not practical for you, consider our liquid alternative. Below, we’ll explain why the dehydrated tea alternative that we clinicians have been led to believe in, while convenient, is low potency. In comparison, our liquid tea concentrates appear unusually strong: Appearances are important. First, we’ll show you why it’s crucial for a clinician to personally test-compare brands for potency. Then, on the VITAL SIGNS page, we’ll show you how very easy it is to do it. You’ll wonder why this wasn’t taught at the university. Hands-on analysis . . .

…It’s a TCM clinician’s responsibility.

Effectiveness vs. Convenience.

Because dehydrated herbal extract concentrates are so lucrative for mass marketers, so accessible for practitioners, and so easy for patients, few educators stray from the path to mention the significant drawbacks. Below, we’ll point out the stark reality.

At the VITAL SIGNS page, forget the brand name, the endorsement, the popularity, we’ll show you how you can tell which products are likely to pay the highest dividends in patient satisfaction, and which have nothing to offer beyond good looks on the shelf.

Similarity and Difference

“Best Quality” – the use of that marketing idiom in advertisements is the most conspicuous similarity between brands. The most conspicuous difference between brands, even popular brands, is the immense variation in respective power levels. Which are stronger and which are weaker? The failure to check could result in a minimum of outstanding clinical achievements.

Clinicians can verify these potency variations with a simple 5-minute test. We’ll show you how to do it. The results speak for themselves: No practitioner should be prescribing the herbal extract concentrate pictured to the right. Why? Because it’s stale and lifeless . . .



Considering how it’s processed, how could the result be any different?

Stale and lifeless – this, in spite of the “USE BY” date claiming that it’s in a good or acceptable state. The taste is what exposed this feeble product – no high-tech analyzing equipment needed. This commonly prescribed herbal extract concentrate formula and highly advertised brand is as it tastes. Imagine it were shrimp tacos processed as follows: Some of its ingredients were overcooked, oxidation began racing from the moment it was dehydrated, it hasn’t been refrigerated, and 4 months later it’s in front of you on the dinner table… Whether dinner or medicine, simply tasting it would reveal that there’s no power remaining. Sure, some bitter or sweet tastes can survive processing excesses, but overall, this medicine is not going to accomplish its TCM goals. It’s ease of administration is irrelevant to the discerning clinician and motivated patient. Finding more effective brands is easy: Check our VITAL SIGNS page.

Distractions can make it easy for a clinician to loose sight of what’s most important.

State of the art manufacturing facilities can produce astonishingly high quantities of dehydrated tea. Then the marketing agencies get creative, showcasing a shiny and complex wonderland of expertise – a distraction that keeps the product from our taste buds where viability can easily be put to the test. To the perceptive TCM clinician, it’s the taste that exposes the medicine’s potential. Over-processed and inadequately preserved, the worst tastes chalk-like, and the weak are the norm. The mass manufacturing of TCM exists to “treat the masses.” And like with TV-dinners, trade-offs accompany the convenience. It’s important that our patients receive a highly potent product and not a product merely posing as one.


Problem: The industrialization of TCM results in pharmacies stocked with herbal extract concentrates that are stale/rancid and losing potency every day. “USE BY” date is unrealistic and misleading. The focus here is on dried products in the pill or powder/granule form (dehydrated tea).

Therapeutic                         Toxic

Many herbs we use in TCM contain a high volume of potent medicinal oils: persica seed/Tao Ren, Armeniacae seed/Xing Ren, 20-30 other commonly used seed varieties, and many other herbs. The changes that happen to the oils after an herb tea is dehydrated is basic science . . .

Cause: The combination of a substance with oxygen (oxidative rancidity). When herbs are cooked, the cell walls are broken, releasing the active compounds out into a bioavailable form. At this point it needs to be preserved with alcohol or frozen. If instead it is dehydrated and left without preservatives, then months later, when it arrives at the clinic, it’s already stale – like would happen to whole wheat flour. The dull taste does not lie. Storing them at room temperature, in non-photoprotective packaging (clear or white bottles), and exposing them to humidity by repeated opening, all accelerate potency decline. These factors make a pharmacy of herbal extract concentrate powders/granules entirely impractical.

  • Spray drying: This common practice should not be glossed over. Fragrance is an obvious statement of power. In the bloodstream, the aromatic property is highly therapeutic and fast acting. While spray-drying is efficient for mass production, it nearly eliminates fragrance – it’s a potency killer. Pills are commonly made from spray-dried powders – and that’s one reason why they barely have any smell at all: Therapeutic potential is exchanged for production speed and mass-marketing.


Solution: Avoid oxidative rancidity and rapid potency deterioration altogether with a liquid herbal pharmacy. It simply makes more sense. Unlike dried concentrates, our cooked liquid tea concentrates (not tinctures) will not go stale/rancid. They’re preserved with 20% alcohol while fresh and at the height of their potency. They don’t need refrigeration and will remain highly potent for years even if they’re opened 50 times a day. When the window of opportunity to intervene is open, they’re always ready at 100% high potency.

The strong taste, revealing a potent medicine, is quite tolerable in a mango juice shot.
