What's Special About DaoDi Herbs?

Every bottle we make starts in a field somewhere. Which field, it turns out, matters a lot. Two herbs with the same name can be wildly different depending on the soil, the weather and when somebody got round to picking them. DaoDi is the old Chinese idea that every herb has a proper home, and it's how we choose ours.

The idea

What does DaoDi mean?

There's no neat English word for it, so let's take the two characters one at a time. Dao (道) originally meant the old districts of the Chinese empire. Think provinces. Di (地) is the earth itself, the soil and the lie of the land.

Put them together and you get something like 'geo-authentic'. A herb grown in the region it's always been grown in, in the conditions that earned it a reputation in the first place. Champagne has to come from Champagne. Same sort of thinking, only a couple of thousand years older.

It goes right back to the Shen Nong Ben Cao Jing, the Divine Farmer's classic of herbs. The book reckoned a herb grown in its right place and picked at its right time is at its very best. China's size helps here. You've got steamy subtropics at one end and proper frozen winters at the other, so the old herbalists made notes. This herb from here, that one from there.

Famous homes

Some herbs and their traditional homes

A few of the best-known examples. In China some herbs are still named after the place they come from.

当归

Dong Quai

Dang Gui

The Min County variety has a reputation all of its own. Cool, high mountain slopes seem to suit it.

Traditional home: Min County, Gansu

黄芪

Astragalus

Huang Qi

The best is said to grow in the dry northern hills, where the roots come up long and sweet.

Traditional home: Shanxi and Inner Mongolia

三七

Notoginseng

San Qi

So tied to one corner of Yunnan that Wenshan proudly calls itself San Qi's hometown.

Traditional home: Wenshan, Yunnan

枸杞子

Goji Berry

Gou Qi Zi

Ningxia goji is the one everybody wants. Long sunny days and the Yellow River do the rest.

Traditional home: Ningxia

地黄

Rehmannia

Di Huang

One of the famous Four Huai Herbs from the old Huaiqing district. Chinese yam is another.

Traditional home: Jiaozuo, Henan

川芎

Chuanxiong

Chuan Xiong

The 'Chuan' bit is short for Sichuan. A herb that tells you where it's from, handily.

Traditional home: Sichuan

人参

Ginseng

Ren Shen

The Changbai Mountains, up on the border with North Korea, are classic ginseng country.

Traditional home: Jilin

白芍

White Peony Root

Bai Shao

Bozhou has been a herb market town for centuries, and its peony root is well known across China.

Traditional home: Bozhou, Anhui

These are the homes the tradition names. Climate and soil shift over time, so where a region changes we'll go to another area that meets the same standard rather than settle for a poorer crop.

Spotting the difference

DaoDi herbs vs look-alikes

CompareGenuine DaoDiCounterfeit material
PricePriced like the real thing, because it isSuspiciously cheap
Where it's grownThe region on the labelSomewhere else entirely
The plantThe right speciesOften a close cousin that looks the part
DryingDried naturallyFrequently sulphur-treated to look brighter
TraceabilityBatch traced back to the fieldNobody's quite sure

Why it matters

Sulphur: twice the shine, half the herb

Because DaoDi herbs fetch a premium, there's money in passing ordinary ones off as the real thing. Bupleurum (Chai Hu) and Pinellia (Ban Xia) have been hit especially hard. Demand's gone up, genuine harvests have gone down, and look-alikes have filled the gap.

Sulphur is the easiest one to show you. It's used to make dried herbs look paler and keep longer. When White Peony root (Bai Shao) is sulphur-treated it forms a new compound, paeoniflorin sulfonate, and in one comparison the main active constituent dropped by more than half. Brighter on the shelf, half as much herb. Not a great swap, is it?

Our approach

How we keep it honest

No magic to it. Just doing things the slow way, with growers we've known for years.

  1. 1Right herb, right placeEach herb comes from its traditional home, or from somewhere that meets the same standard if conditions there change.
  2. 2No sulphurEvery herb we use is 100% natural and never sulphur-treated. Full stop.
  3. 3Traced to the fieldLong relationships with the same growers mean we can tell you where a batch came from, not just promise it's good.
  4. 4Tested properlyOur formulas are made to GMP standards and SGS check them in the lab.

Questions

DaoDi herbs: your questions

Can't find your answer? Drop us a line.

What does DaoDi actually mean?

Roughly 'geo-authentic'. A herb grown in the place it's traditionally grown, the way it's always been done there.

Does it really matter where a herb is grown?

We think so, yeah. The ground it grew in and the day it got picked both change what's inside. Same name on the label, very different herb in the jar.

How can I tell if a herb's been sulphur-treated?

Not easily, frankly. A suspiciously bright, pale look is one clue, and sometimes there's a sharp whiff. Honestly though? Buy from people who'll tell you where it came from.

Are all Aura herbs DaoDi?

Every herb we use is sourced on the DaoDi principle and none of them are sulphur-treated. That goes for the tablets and the teas.

Where can I see what's in each formula?

Our herb glossary lists every herb in the range and which formulas it turns up in.
