The first several years I had an OMMP card, or Oregon Medical Marijuana Program, I was lucky enough to find an expert master gardener, and lifelong cannabis consumer. She guided what I already knew, and taught me so much more. Because of this wonderful garden fairy, who plants a circle colibrí garden with sweet lilies, cannabis, jasmine, and honeysuckle vines, just to attract the two varieties of hummingbirds in our region of the Pacific Northwest.

My first welcome into her warm, wood-heated kitchen included two jars of glycerin tincture: a single-infusion and a darker double-infusion. I thought glycerin, or glycerol, was for the skin in beauty products, or a surfactant in soaps! Little did I know about food-grade, vegetable glycerin processed from palm, soy or coconut. Slightly sweeter than honey to my palate,  straight a teaspoon tasted like a cannabis cough syrup, but in tea it added just a hint of sweetness.

If you have access to cannabis flower, you can easily provide this multipotent, medicine for your family. Even better, You get to control the experience.  Choose if the medicine creates a high for the user or not, in one small step. To get a high with your edible, decarboxylate the bud first.

You will need a quantity of cannabis flower and food-grade vegetable glycerin, easily found in health food stores or online. I like to use a full ounce of bud, or trim and stems, for a quart jar of glycerin. The most useful, family appropriate medicine utilizes the dry, green cured buds directly with the glycerin. Just crumble into budlet pieces or down to the size of a calyx and cover, put in the sterile jar and cover with glycerin.

If you are a 420 family, now is the homeschool, science experiment to watch as the glycerin infuses with the  flower; small bubbles magically arise. Then discuss the viscosity of glycerin while inverting the jar and mixing the contents.


Keep in a dark place with a steady temperature; room temperature best. Once a day for a month, turn the jar on end. If you forget about it, it won’t hurt anything. I’ve left some infusing for months… it does not increase potency after a certain point. Possibly, the flower breaks down a bit more, so slightly more plant material would remain in the tincture after straining the mixture. 

After a month of infusing, strain through a tea sieve into another clean, sterile jar.  Now you have a single-infusion, multipurpose medicine. It soothes all varieties of gastrointestinal discomfort and pain from end to end. Topically, it soothes rashes and and nourishes the skin with antioxidants. As a burn protectant, you’re adding the antimicrobial and antiinflammatory benefit, speeding healing. Imagine as an acne treatment… completely natural!

Online calculators can help you figure out the approximate dosage of a cold-infusion based on the percentage of THC in the bus and ratio of flower to glycerin.  Since I use my untested homegrown… I estimate, based on the tests of my plants parentage… usually between 5-15 milligrams of THC in a teaspoon.

How to decarboxylate your marijuana flower:

For the benefits of the high, decarboxylate your cannabis bud first. Slowly baking it,  allowing the THCA to convert into THC, or Δ9-tetrahydrocannabinol, for a headier experience or stronger sleep aid.

  1. Heat the oven to 225 degrees Farenheit. This method will fill the air with a toasty, weed smell, so plan your children’s playdate accordingly.
  2. Take a baking sheet; we line ours with parchment to not lose a trichome! Gently crumble the flowers with your fingertips. Keep small plant pieces. (Try not to pulverize… we’re infusing not making a paste!)
  3. Bake for 30-40 minutes. Ovens can vary in temperature and rack placement so if the flower gets too brown or smells sharp instead of toasty, check it!
  4. Let it cool while you pour water over a jar and it’s lid to sterilize.
  5. Put the decarbed bud in the jar; cover with glycerin.
  6. Keep the jar in a dark spot at room temperature. Turn the jar on end once a day for a month.
  7. Strain bud through a tea sieve or cheesecloth into a clean, sterile jar. Make sure to identify this jar as the psychoactive medicine tincture. It will taste a bit more weedy than the fresher, sweet-tasting version of glycerin tincture. 

Please let me know about your experiences both making this marvelous medicine and utilizing, whether for healing, recreating or entheogenically.

Of interesting note about Glycerin as an ingestible: 

Glycerin does not cause tooth decay. A major benefit to using vegetable glycerin in your morning beverage is in its structure. The body metabolizes glycerin differently and can even be used as a sweetener in low carbohydrate foods.
