The number of herbs in Tibetan formulas

Understanding Tibetan Formula Structure and Composition

Like other systems, Tibetan Medicine often contains the number of ingredients within the name of the Formula.

But most particular in Tibetan Medicine they have a “families of formulas”, all named after the main herb, along with the number of ingredients following, for example, Chebula 8, Chebula 15, Chebula 25 etc.

In many instances, the family and primary herb are particularly used for a specific condition or to treat a specific organ or humor. The formulas within that family tend to be for more simple and perhaps more acute conditions, with larger formulas containing 25 or more herbs being most typically used for chronic and complex versions of that class of disease. Complex cases often have multiple disorders with opposing energetics and humors combined into one condition, thereby requiring more herbs to achieve the desired result.

This is a very good representation of the need for larger formulas in some instances. And by studying Tibetan Formula Families you can see how other herbs or groups are added to build a formula used for more complex conditions.

You can notice that virtually all formulas with more than 20 or 25 ingredients will contain both Triphala (Three Fruits) and the “Six Excellent Medicines”. This combination of 9 herbs helps promote balance between the Humors and the 5 Organs. This combination is commonly added in the treatment of complex conditions as seen in the larger formulas of Tibetan Medicine.

Another thing noted is that large formulas for chronic conditions of any of the organs often contains medicine to move Blood and resolve stasis. Chronic Inflammation, Pain and Dysfunction invariably has an aspect of blood stasis, and improving circulation is bound to be beneficial if not necessary in the treatment of any chronic condition.

So what we can note is, that large formulas don’t just add “more herbs to treat Asthma”, if it’s a formula to treat Asthma. But actually they are building levels and degrees into the Formula family, depending on what we’re treating. A more simple formula for a simple and acute condition, a large formula for a chronic and complex condition.

In Tibetan medicine, the structural architecture of a formula is as precise as a legal or military hierarchy. This framework explains how Tibetan physicians scale a formula from 3 ingredients up to 35 or more without the herbs conflicting with one another.

1. The Royal Hierarchy

Every Tibetan formula, regardless of size, is structured like a royal court. As the number of ingredients increases, this court expands from a tiny strike team into a massive governing body: It must be pointed out that this is remarkably similar to TCM which also has a Royal hierarchy, denoting the primary herb as “Emperor”.

The King (Gyalpo): The primary herb that directly attacks the root cause of the disease. In Agar-35, Agar (Aloeswood) is the King.
The Ministers (Blonpo): Herbs that support the King. They either amplify the King’s main action or treat the secondary symptoms accompanying the disease.
The Retinue (Khor): Herbs added specifically to eliminate side effects. If the King herb is highly heating, a Retinue herb with a cooling nature is added to protect the body from excess heat.
The Servants/Guides (Tanyig): Herbs that act as guides. They possess a natural affinity for specific organs or channels, carrying the entire formula directly to the heart, lungs, kidneys, or brain.

2. The Law of Harmonics (The Six Tastes)

When formulas grow past 15 or 20 ingredients, Tibetan pharmacology stops looking at individual herbs and starts looking at Taste Harmonics. Sowa Rigpa classifies all herbs into Six Tastes (Sweet, Sour, Salty, Bitter, Pungent, and Astringent). Each taste is mapped to specific elements and humors.

Low Numbers (3–7 herbs): Dominated by one or two distinct tastes to force a rapid shift in the body.
High Numbers (25–35 herbs): Designed to balance all six tastes simultaneously. By including a calculated ratio of all six tastes, the formula becomes “neutralised” in terms of harshness, allowing it to stay in the body for long-term healing without damaging the stomach or liver.

3. The Meaning of Specific Numbers

Beyond the broad categories, specific numbers in Tibetan medicine carry very precise structural meanings rooted in foundational texts:

Formulas ending in 3 (e.g., Triphala/Three Fruits): These represent the ultimate universal balancing act. They almost always target the three core humors (Wind, Bile, Phlegm) simultaneously at a digestive level.
Formulas of 5 or 6 ingredients: These are frequently built around the “Five Elements” or the “Six Excellences” (Zangpo Drug), which are six specific spices (like nutmeg, clove, and cardamom) chosen specifically to protect and support the five vital organs (Heart, Lungs, Liver, Spleen, Kidneys) and the life-force channel.
Formulas of 25 ingredients: This number often signifies a complete expansion of a base formula to cover all five elements across all five vital organs (5 times 5 = 25). It represents a fully comprehensive grid that treats a specific disease across the entire physical anatomy.

4. Synergy within Formulas

In modern Western pharmacology, mixing 35 drugs would create dangerous interactions. Tibetan medicine avoids this through a pharmaceutical process where herbs are ground together into a unified powder (Churna) or pill (Rilbu).

In Tibetan Medicine and indeed all the Traditional Medicine systems, a compound of numerous herbs isn’t looked at as a compound of numerous herbs. Rather, it’s viewed as a single, unified entity, which, like individual herbs, has its own temperature and taste. This is evident by the fact that a single herb, taken in powder, may be given in a dose of 1 dram (3.8 grams) in the Western Tradition, but that herb being used in a compound with a number of other herbs tends to be also taken in the same dose of 1 dram.

The compounding of a formula means that the chemical constituents bond into entirely new, complex compounds during manufacturing. The high number of ingredients actually dilutes the toxicity of any single potent plant, making high-number formulas remarkably safe for long-term chronic care.

One of the most classic and extreme example of this in Tibetan Medicine would be the Aloeswood 35 formula. This formula, containing 35 ingredients, is viewed as a regulating tonic medicine for those of a rlung (Wind/Vata) constitution, and is commonly dispensed as a general health tonic for such individuals. What’s remarkable, however, is the fact that it contains both Nux Vomica and Aconite in their processed (detoxified) forms; two of the most potent, and potentially, most toxic medicines in the traditional Materia Medica.

Here is a break-down of Tibetan Formula families:

Low-Number Formulas (3 to 9 Ingredients)

Examples: Triphala (3), Aloeswood 8, Tabasheer 9

What they have in common: More simple in effect, having a Targeted, high-intensity action.
The Clinical Thread: These formulas are designed for rapid, direct, and unhindered intervention. Because there are fewer ingredients, the dose of each individual herb is much higher.
How they work: They are almost always deployed for acute, single-humor crises. For example, Aloeswood 8 is a concentrated strike directly against acute “Wind” (rlung) imbalances like sudden panic attacks, insomnia, or sharp nervous system disruptions.
The Structural Hierarchy: They feature a clear “King” ingredient (the primary therapeutic herb) and a small, tightly controlled “Retinue” of herbs designed strictly to guide that King herb to a specific organ or channel

Mid-Number Formulas (11 to 19 Ingredients)

Examples: Clove 11, Golden 11, Chebula 18

What they have in common: Organ-specific effects, balancing
The Clinical Thread: These formulations represent the “workhorses” of everyday clinical practice, specifically targeted toward sub-acute conditions and specific internal organs.
How they work: Formulas in this range usually handle localized, multi-layered problems—such as respiratory inflammation involving both “Phlegm” and “Heat” (Phlegm-Bile imbalances).
The Structural Hierarchy: At this tier, the formula structure expands. You still have the King ingredient, but the retinue now includes secondary active groups that work to harmonise digestion (the digestive fire), ensuring that the primary medicine can actually be absorbed and processed by the targeted organ without upsetting the stomach.

High-Number Formulas (20 to 35 Ingredients)

Examples: Camphor 25, Aloeswood 35, Chebula 35

What they have in common: Balancing Humors, systemic harmonisation involving multiple organs and humors.
The Clinical Thread: These formulas are systemic modulators designed for chronic, deeply rooted, or highly complex conditions where multiple bodily systems are failing simultaneously.
How they work: When a disease becomes chronic, it shifts from affecting just one humor to disturbing all three (Wind, Bile, and Phlegm) simultaneously. High-number formulas contain balanced “hot” and “cold” herb clusters deliberately woven together to treat one issue without causing a flare-up in another. For instance, Agar-35 treats deep, systemic neurological or circulatory issues while shielding your digestive and metabolic health.
The Structural Hierarchy: The King ingredient is supported by a massive matrix of herbs. Rather than just guiding the medicine, dozens of secondary ingredients are added specifically as antidotes to neutralise the toxicities or harsh side-effects of the other herbs in the pill.

Ultra-High Number “Precious” Formulas (50 to 100+ Ingredients)

Examples: Rinchen Ratna Samphel (70), Rinchen Mangjor Chenmo

What they have in common: Total cellular detoxification and rejuvenation.
The Clinical Thread: Known as Rinchen Rilbu (Precious Pills), these are the crown jewels of Tibetan pharmacology. They are used for severe, life-threatening conditions, toxic poisoning, or complete constitutional collapse.
How they work: They do not just target an ailment; they reset the body’s entire energetic blueprint.
The Structural Hierarchy: Herbal matter alone cannot sustain this level of complexity. These formulas are fundamentally tied together by the integration of purified, detoxified minerals and gemstones (like gold, silver, turquoise, and coral) alongside massive botanical profiles. The metals act as powerful stabilisers, allowing dozens of diverse botanical compounds to stay bound and synergistic over long periods of time

Another aspect for Consideration

Many years ago, a Tibetan Doctor told me that in the past (as today) many Tibetans lived very remotely, either as nomadic herdsmen or in small villages very far from any town or center. In these times, if someone was ill, they would either make the long journey to a doctor, often in a monastery, or perhaps were lucky enough to have a wandering physician visit their village or camp.

Because the person may have needed months of treatment but were perhaps unable to repeatedly see the doctor over a course of time, it was necessary to develop formulas that may treat the presenting condition, while simultaneously guarding against any negative effects that treatment may have over a prolonged period.

For example, if someone had a Heat condition and you used cold, bitter medicines, within a short period of time the person may be relieved of their heat condition, then those same cold, bitter medicines may quickly have a negative impact. So by creating formulas that combined Cold medicines along with warming medicines, not only would the heat condition be resolved more quickly (due to the enhanced efficacy provided by the warming medicines), but the warmth (Yang) of the body would be protected.

Practically, the physician may have used a strong, cold formula with fewer ingredients to immediately sedate the excess heat, but then prescribe a formula that had cooling aspects, along with warming, balancing and harmonising medicines to be taken over a longer period of time to prevent recurrence.

This is why many of the larger formulas treat and respect the different humors and organs of the body simultaneously illustrated most perfectly by the widespread use of Triphala, the three fruits that, when used together, predispose the body to balance.

Despite the fact that Tibetan Medicine has many of its foundational theories based on the Ayurvedic tri-dosha framework (Vata/Pitta/Kapha–Wind/Bile/Phlegm), the pharmacology and formulas of Tibetan Medicine are distinctly unique, and, from my point of view, generally stronger.

This shows why studying other traditions can give greater insight into new ideas in the composition of herbal formulas, and different concepts in the treatment of various conditions.
