Your Health? Grow A Medicinal Garden, Preserve Tinctures with Glycerin, De-Power Big Pharma

stock here: I have made tinctures, using Olive Oil, or Vodka. good friends came by for a party and a garden walk, we I learned that Glycerine is an even better Tincture medium for many things. Here is the backgrounder for you.

I’ll be making some Feverfew in Glycerine, before winter comes. Feverfew is a huge plant, with massive, vigourous flowers that pollinators love. It really took over my raised bed medicinal garden, by sheer size, so I will want to make several pints that can be preserved for at least several years. I may plant it “wild” somewhere nearby.


This is a good question. Whether or not something can be safely stored at room temperature depends on several factors – these can include the acid level (pH), available water (water activity), and quality changes due to light or oxidation. The type of packaging used, the presence of oxygen in the package, and many other things will also impact the quality of your product long term.

For your tincture, the primary component that could make your product shelf stable (able to be stored at room temperature) would be to control the available water.  This is accomplished with the glycerin. High levels of glycerin (greater than 55% of the total volume or higher) will keep the available water of your tincture low enough (water activity <0.75) that it will not mold. If the glycerin content is lower than 55%, then it would likely mold.  If the glycerin content is too low (less than 25%), then there is enough water available that some of the bad bacteria (pathogens) could grow in your tincture (and it would likely mold).

From a chemical perspective, some of the beneficial components in your tincture will breakdown with light exposure, at higher temperature (room temp versus refrigerator), and over time. Therefore, the quality of your tincture would be the highest if you stored the tincture in a dark container and in the refrigerator.
