黄帝内经 Huángdì Nèijīng

The Yellow Emperor’s Inner Classic · third to first century before our era

The theoretical bedrock: Yin and Yang, the breaths, the seasonal correspondences. It describes almost no plant, but gives the frame within which all of them will be classified.

神农本草经 Shénnóng Běncǎo Jīng

The Divine Farmer’s Classic of Materia Medica · first to second century

Three hundred and sixty-five entries, one for each day of the year, set out in three ranks. It is the first systematic classification of Chinese plant matter.

本草纲目 Běncǎo Gāngmù

Li Shizhen · completed in 1578, printed in 1596

One thousand eight hundred and ninety-two entries in fifty-two books, the fruit of twenty-seven years of work. The summa of the pharmacopoeia, and the reference from which most of the classifications this catalogue carries descend.

植物名实图考 Zhíwù Míngshí Túkǎo

A botanical collection engraved on wood, remarkable for the precision of its plates. It is those plates, traced and reworked in the house ink, that illustrate the collections on the site.

Plate one

A system for reading the living world

The TCM tradition rests on a patient observation of nature, refined over more than two millennia. Where modern thought isolates a single molecule, it reads each plant as a set of qualities: its temperature, its taste, its orientation, its resonance with the seasons.

This grid of reading is not a science in the contemporary sense: it is a cosmology, a coherent way of ordering the living world, handed down from generation to generation by the great treatises, from the Huangdi Neijing (the Yellow Emperor’s Inner Classic) to Li Shizhen’s Bencao Gangmu, the summa of the pharmacopoeia completed in the sixteenth century. To understand these markers is to understand the logic of the BotaQi catalogue: every product listing carries their trace.

Four markers are enough to place a plant in this system: its thermal nature, its flavours, the Phases the tradition attaches it to, and the category of the pharmacopoeia it is filed under. The chapters that follow take them one by one; the last shows where to read them on a listing.

Qi qì
Often translated as breath. The dynamic weave which, according to the tradition, animates all things; the word gives the house its name.
Bencao běncǎo
Literally roots and herbs. The Chinese name for materia medica, and by extension for the literary genre that has recorded it for two millennia.

Yin, Yang and Qi

Figure

The Supreme Ultimate and its eight pairs

  • Yin side Yang side
  • The shade The light
  • The north The south
  • Rest Impulse
  • Winter Summer
  • The descent The rising
  • The inside The outside
  • Coolness Heat
  • Night Day

阴 Yin yīn

The shaded side

The character draws the shaded side of the hill. It names what descends, gathers in, cools and keeps. It does not stand against the Yang: it holds it in seed, and turns into it.

阳 Yang yáng

The sunlit side

The same relief, but in the sun. It names what rises, unfolds, warms and sets in motion. The pale dot at the heart of the dark half says that neither of the two exists pure.

气 Qi qì

The breath

What circulates between the two sides. The old character shows the steam rising from cooking rice: a matter in movement, neither solid nor empty.

Plate two

Yin, Yang and Qi

Everything, in Chinese thought, is read through the pair of Yin and Yang: shade and light, rest and impulse, coolness and heat. Neither opposed nor fixed, they complete one another, turn into one another and answer one another: the figure of the taiji draws their perpetual movement.

Between them circulates the Qi (气), often translated as “breath”: the dynamic weave which, according to the tradition, animates all things. The seasons, the hours of the day, foods, plants: everything is described as more or less Yin, more or less Yang, and by the way its breath unfolds. This is the vocabulary you will find everywhere on BotaQi, right into the reading offered by Nuwa, our guide.

The pair does not sort the world into two camps: it situates. A plant is never Yin in itself, it is more Yin than another, at a given moment, under a given gaze. That is why the catalogue never carries the mention on its own: it would have no term of comparison. What it carries are the scales of the three chapters that follow.

Taiji tàijí
The Supreme Ultimate: the name of the circular figure where the two sides fit into one another. It stands not for a fixed balance but for a rotation.
Wu Xing wǔ xíng
The five Phases, which take over from the pair to describe the passages rather than the poles. Plate five.

寒 Cold hán

The coldest register of the tradition

The most Yin degree of the scale, its coldest register. The tradition ties it to the descent and to the heart of winter.

凉 Cool liáng

A gently cooling register

One step short of cold, a gently cooling register. Many flowers and many leaves carry this degree.

平 Neutral píng

The tempered middle

The middle of the scale, neither markedly Yin nor markedly Yang. The tradition holds it to suit every terrain, and gives it the part of accompanying the others.

温 Warm wēn

A moderately warming register

The first degree of the Yang side, a moderately warming register. The tradition ties it to the impulse and to the rising of spring.

热 Hot rè

The deepest warming register

The most Yang degree, the deepest warming register. The tradition ties it to the coldest seasons, and files only a small number of plants there.

Plate three

The thermal natures

In TCM, every plant has a “nature”: a thermal leaning the tradition associates with it, independently of its actual temperature. Five degrees are distinguished, from the most Yin to the most Yang: cold, cool, neutral, warm and hot.

A plant of cool nature is traditionally associated with the Yin side: the loosening, the descent, the coolness; a warm or hot plant with the Yang side: the impulse, the rising, the heat. The neutral nature, in the middle, is held to suit every terrain. On each product listing, a coloured dot shows this nature at a glance.

The scale below is the catalogue’s own: five degrees, five inks, from the blue of the cold nature to the burnt earth of the hot nature. They are the same five inks on a product card, on its listing and in the filters; they never vary from one page to the next.

Nature xìng
The thermal leaning a plant carries in the traditional classification, independent of its actual temperature and of that of the infusion.
Four breaths sì qì
The old name of the scale: cold, cool, warm, hot. The neutral, added later as a middle, makes five.

The five flavours

Figure

The wheel of the five flavours

酸苦甘辛咸 五味

酸 Sour suān

gathering, holding in · Wood · Spring

What gathers in and holds. The Wu Mei plum, smoked and intensely sour, is the clearest example in the catalogue: there, taste and classification say the same thing.

苦 Bitter kǔ

drying, downward movement · Fire · Summer

What dries and sends downward. A flavour the tradition doses sparingly, and readily ties to clarity rather than to pleasure.

甘 Sweet gān

tempering, slowing · Earth · Between seasons

What tempers and slows. It is the most frequent flavour of the pharmacopoeia: Gan Cao liquorice, whose name means sweet herb, enters a great many formulas for that reason.

辛 Pungent xīn

dispersing, outward movement · Metal · Autumn

What disperses and sets in motion. Barks and aromatics carry it: aged mandarin peel Chen Pi shares it with the bitter.

咸 Salty xián

softening, reaching into the depths · Water · Winter

What softens and reaches into the depths. The rarest of the five in the catalogue, where it belongs above all to marine and mineral matter.

Plate four

The five flavours

The tradition distinguishes five fundamental flavours: pungent, sweet, sour, bitter and salty. More than a taste in the mouth, each flavour describes in Chinese thought a direction of the breath: the pungent disperses, the sweet tempers, the sour draws in, the bitter sends downward, the salty carries into the depths.

Each flavour is moreover attached to one of the five Phases, which is why you will often see them side by side on our listings. One and the same plant frequently carries two or three flavours: it is their combination that makes its identity.

Perceived taste and classified flavour often coincide, but not always: the Wu Mei plum is sour in both senses, Gan Cao liquorice is sweet in both senses, but elsewhere it is the traditional classification that prevails over the mouth. On a BotaQi listing, it is always the classification that is given.

Flavour wèi
Less a taste than a direction attributed to the breath. A plant often carries two or three: it is their combination that makes its identity.
Bland dàn
A sixth flavour, held by the tradition as an extension of the sweet. The catalogue mentions it when the source mentions it.

Plate five

The Five Phases

The heart of the system is the theory of the Wu Xing (五行), the five Phases, sometimes called the five elements: Wood, Fire, Earth, Metal and Water. Less substances than dynamics: Wood evokes the rising of spring, Fire the fullness of summer, Earth the centre and the turns between seasons, Metal the gathering inward of autumn, Water the depth of winter.

The Phases engender one another in an endless cycle (Wood feeds Fire, Fire produces Earth, Earth holds Metal, Metal enriches Water, Water makes Wood grow) and temper one another through a second cycle, called the control cycle. Each corresponds to a “sphere” of correspondences, and plants are traditionally attached to one or several of those spheres. It is this grid that structures our classification, and the reading of your “inner season” that Nuwa offers. Each card below opens the selection for the matching Phase.

To each Phase the tradition attaches a season, an orientation, a climate, a colour and a flavour. The table below gives the five most stable columns: they are enough to read a classification, and that is the only use this guide makes of them.

Generating xiāng shēng
The circle: Wood feeds Fire, Fire produces Earth, Earth holds Metal, Metal enriches Water, Water makes Wood grow. Without beginning or end.
Controlling xiāng kè
The star that crosses the circle: each Phase tempers another, so that the cycle does not run away with itself.

The twenty-four breaths

Plate six

The twenty-four breaths

The traditional Chinese calendar doubles its count of lunations with a solar division: twenty-four segments of about a fortnight, the jieqi (节气), literally the “nodes of breath”. They follow the course of the sun, so they fall on the same dates each year to within a day, and since the Han they have formed the farming calendar of China.

Each fortnight bears a name that describes the state of the world rather than a date: Waking of Insects, White Dew, Frost’s Descent, Major Snow. Four of them open the seasons, four others mark the solstices and the equinoxes; the sixteen that remain name the passages. The tradition reads the year in this sequence, and ties to it ways of dressing, of cooking and of working the land.

BotaQi shows the current breath at the head of the home page, together with the reading the tradition gives it. All twenty-four are gathered below, in the order in which they fall.

The Chinese calendar therefore runs on two clocks. The lunar one sets the months and the feasts: New Year, the Lantern Festival, Mid-Autumn fall on a different Gregorian date each year. The solar one, the one of the breaths, sets the seasons and the work of the land, and shifts by no more than a day from one year to the next. Almanacs print the two side by side. The index below follows only the second, one season to a row, opening at the Beginning of Spring.

Jieqi jiéqì
Node of breath: one of the twenty-four segments of the solar calendar. The word node says the passage from one state to another, like the node of a bamboo stem.
Pentad wǔ tiān
Each breath divides into three pentads of five days, each described by a sign borrowed from the plants, the beasts or the sky. Seventy-two in all for the year.

The three names

The French name, the Chinese name and its pinyin transcription, then the Latin name of the matter. The search bar of the site understands all four.

The thermal nature

One of the five degrees of plate three, named in full and carried by its coloured dot. Clickable: it opens the plants of the same nature.

The flavours

One, two or three, in the order the sources give them. These are the flavours classified by the tradition, not those the mouth will perceive.

The Phases

One or several, among the five of plate five. Each opens the collection of the matching Phase.

The category of the pharmacopoeia

The family the treatises file the plant under. Thirty-three families cover the whole catalogue, and each has its collection.

The format and the price

The net weight, the price brought back to one hundred grams and the batch reference, which makes it possible to trace the origin of the bag.

The note of caution

It appears on every listing: the information describes a traditional use, given for cultural and informational purposes, which constitutes neither a health claim nor medical advice.

Plate seven

Reading a BotaQi listing

On each product, these markers are gathered into a clear profile: the French name, the Chinese name and its pinyin transcription; the thermal nature; the flavours; the Phases; the category of the pharmacopoeia to which the tradition attaches the plant.

The profile chips are clickable: one click on “Warm”, “Bitter” or “Earth” opens the selection of all the plants sharing the same quality, an invitation to explore the catalogue by affinity, the way one leafs through a herbarium. And if a name comes back to you in pinyin, in English or in Latin, the search bar understands them all.

The listing reproduced here is that of a real product from the catalogue. Seven markers are numbered on it: the three names, the nature, the flavours, the Phases, the category, the format with its price, and the note of caution that accompanies every page of the site.
