Shénnóng Tastes the Hundred Herbs

His body is like jade held up to light.

This is not metaphor. The tradition is literal about this: Shénnóng’s torso is transparent, his organs visible through his skin, his stomach and intestines and lungs watching everything that enters. He designed himself this way, or he was made this way, or his body evolved this way because what he was going to do required it. He needed to see what the plants did. Not be told. See.

The people are sick and they do not know why. They eat things that help them and things that hurt them and they cannot tell the difference until too late. They eat the red berries that stop the heart. They avoid the gray-green leaves that stop the fever. They have no way to know, except to try and die, and dying is a slow way to build a pharmacopoeia.

Shénnóng decides to build it differently.

He goes into the mountains.

He takes each plant in turn — root, leaf, flower, bark, seed, stem — and he eats it. He watches through his own body what happens. The jade walls of his stomach show him the plant taking effect: which ones turn the inner landscape red with heat, which ones cool it blue, which ones cause the liver to contract, which ones stimulate the stomach’s movement, which ones stop the breathing, which ones clarify the blood.

Seventy-two times in a single day, by the account in the Huainanzi, he is poisoned. Seventy-two times in a single day he cures himself — because he can see the poison and because he has, by now, found enough antidotes to have a small toolkit. He is simultaneously the experimenter, the experiment, the laboratory, and the laboratory assistant watching through the window of his own chest.

The accounts describe one day in particular when he tasted seventy herbs and was poisoned by sixty-seven of them, and the antidote for each poisoning was one of the other herbs he was also tasting that day. The system saved him. He had, by accident or design, arranged his experimental day as a kind of pharmacological self-regulating loop in which the cures were entangled with the poisons and the sequence of tasting was itself the therapy.

He does not die. Not from this. Not from the hundred herbs or the hundred poisons or the seventy-two daily poisonings that become legendary. He dies, eventually, from the intestine-splitting grass — from the one plant that works faster than his transparency, faster than his ability to identify and counteract, the plant whose damage is done before he can see it clearly enough to name it.

But before the intestine-splitting grass, before the end, he gives humanity the tea plant.

The tradition assigns to Shénnóng the discovery of tea: he was boiling water in the field one day — he insisted on boiling his water, a knowledge of contamination that is itself part of the medical system he was building — and some leaves from a nearby bush fell into the vessel. He drank the infusion. He watched through his transparent body what it did to him. He tasted: bitterness, then clarity, then a lifting in the chest that was not the lifting of stimulants but the lifting of something being unblocked.

He added it to the catalogue.

The catalogue becomes the Shennong Bencao Jing — the Divine Farmer’s Materia Medica — completed in the Han dynasty, attributed to him in the way that foundational texts are attributed to the founding figure who made them possible. Three hundred sixty-five substances, organized by the three classes that will define Chinese pharmacology: the upper class of tonics that strengthen without harm, the middle class of substances that treat illness but require care, the lower class of poisons that kill disease if the dosage is exact.

He knew the dosage because he had it in his body. He had been the dosage. He had swallowed every number to find it.

The mountains are still full of what he tasted. The healers who follow him, for the next five thousand years, will go back to the same mountains to find the same plants, and will apply to those plants the same transparent attention that Shénnóng modeled — the willingness to look closely enough at what is happening inside that you can finally know what to recommend.
