Notoginseng Root (三七) — Complete Guide

What is Notoginseng Root?

Notoginseng Root (三七) is the dried botanical known in the Western trade as Panax notoginseng. In the Chinese materia medica it is classified as warm in nature and sweet,micro-bitter in flavour, and it is assigned to the Liver, Stomach meridians. Those three attributes — temperature, flavour and meridian affinity — are the vocabulary traditional practice uses to describe what a substance does in the body.

Commercial material is grown or wild-collected mainly in Wenshan, Yunnan, China. The part of the plant that is harvested, the season it is collected, and how it is dried all change both the appearance and the measured content of active constituents, which is why two lots of the same species can differ substantially in price.

How it is classified

What it is used for

Traditional texts describe Notoginseng Root as a herb that stops bleeding. It is most often considered when a person presents with trauma with swelling, and it appears in formulas for bleeding.

Those uses are the historical record, not a claim of clinical efficacy. If you are treating a medical condition, the herb belongs in a plan reviewed by a qualified practitioner who knows your history and your other medications.

Where it sits in the wider materia medica

Chinese materia medica is organised by function rather than by plant family. Notoginseng Root sits among the herbs whose primary role is to stops bleeding, which places it in a working group rather than a botanical category. Two plants that look nothing alike can sit in the same group; two close relatives can sit in different ones.

That organisation matters when you are reading a formula. A practitioner building a prescription starts from the pattern, then selects herbs by function and temperature, then adjusts ratios. Notoginseng Root, being warm and sweet,micro-bitter, is chosen when the pattern calls for that profile — not because it is the strongest option available, but because it fits.

It also explains why substituting one herb for another is not straightforward. Two herbs in the same functional group can differ in temperature, in which meridian they reach, and in how harsh they are on digestion. Notoginseng Root reaches the Liver, Stomach meridians; a substitute may reach different ones and change the direction of the whole formula.
