Artemisinin and the cold recipe

Status: analogy and design idea. Nothing on this page is a finding about cannabis or about any product.

The recipe

About 340 CE, Ge Hong wrote the Zhouhou Beiji Fang, a handbook of prescriptions for emergencies. For intermittent fevers it says, in the words Chemistry World gives: take a handful of qinghao (sweet wormwood), immerse it in two sheng of water, wring out the juice, and drink it all.

Most traditional recipes of the time called for boiling the herb. This one does not. Sixteen centuries later, Tu Youyou, working in China's Project 523 to find a malaria treatment, noticed that the text never says to heat the water, and asked whether her team's extractions had destroyed the active ingredient. Her team switched to low-temperature extractions, and the ether extract was the most active against the malaria parasite in mouse models. The compound is artemisinin. Tu's own account is in Nature Medicine (doi:10.1038/nm.2471).

The story has limits, and they matter. It is not simply "raw beats heated": a later step, treating the extract to remove acidic impurities, is credited as the critical one. And it is artemisinin, from a different plant. It says nothing about whether cannabis is a dietary requirement.

What it is used for here

One thing carries over, as a design instruction and not as evidence: handle the plant as little as possible, and do not heat what you have reason to think heat will change. That is the same instruction the book gives for hemp seed and raw cannabis leaf and flower (The Kitchen Pharmacist).

It also makes a second point, which the author wants kept in view: cannabis is not the only plant that may carry something the body can use. Artemisinin comes from Artemisia annua. The book notes that the amorfrutins, compounds from edible legumes, bind the same site on PPAR-gamma that THCA does. Whatever is eventually shown for cannabis, the question of what plant foods carry is wider than one plant.

Total Synergy

Total Synergy is the author's working name, not trademarked, for a cold-processed preparation of hemp seed and raw cannabis leaf and flower, made on the minimal-handling principle above. It is an idea that has not been brought to market. The knowledge behind it is posted openly, with credit to Ge Hong's text and to Tu Youyou's account of it.

No results for any preparation are claimed on this site. The evidence stage is the one stated for the book: hypothesis, with the authors' own preprint reporting that the essentiality criteria are not met (ledger L21).

The nutrition half, in the kitchen

Total Synergy has two halves: raw cannabis leaf and flower, and hemp seed. Only the hemp-seed half is written up here, due to regulatory limits in some locales regarding use of high-proof ethanol as well as certain plant materials. The steps are the book's own, from The Kitchen Pharmacist, and nothing here is new.

1. Use hulled hemp seed (hemp hearts). The book's daily guideline is two tablespoons per meal for women and three for men. That is a guideline in the book, not a tested dose.
2. Heat is not the issue for the seed. Unlike raw cannabis, hemp seed does not need the cold rule: the book says its fatty acids are more heat-stable, so it can go in the pot or the pan. The cold-blended drink is simply the easiest way to take it with nothing heated at all.
3. Cold-blend it. Run the seed in a blender with water and flavouring for about a minute, until smooth. Drink it fresh or keep it refrigerated for up to four days, and shake it before pouring. The full recipe, with quantities and its credit to Elaine Gordon, MPH, is Chocolate Hemp-Seed Milk in The Kitchen Pharmacist.
4. Take it with a meal that has some fat. The book says the fat-soluble parts are absorbed better that way.
5. Add vitamin B12 from another source. The book notes that neither hemp seed nor raw cannabis supplies enough of it.

Why hemp seed is the food half is argued on Breast milk and hemp seed plus raw cannabis, side by side. That comparison is an observational review, and the author plans to revisit it for rigor and to examine hemp sprouts. It is not a finding on this page.

Not published here

• Cold-pressed hemp seed oil. The author's notes list it as part of the full idea, but no method for it has been written up, so none is given.
• A home extraction of the cannabis half. It works with high-proof ethanol. A draft exists, has not been reviewed, and is not published on this site. Raw leaf and flower appear only as food handling in the book, under its status banner. Cannabis is controlled in many places.

What would defeat the analogy

The point of the analogy is that cold handling kept an activity that heat removed. It fails as a guide to cannabis if the acidic compounds turn out to be stable under the conditions a kitchen or an extractor actually uses, or if the benefit of eating the plant does not depend on the acidic form. Both are open, and both are testable.
