The purpose of this kit is educational, so we try our best to keep it super simple and teach one method of tincture making. Using glycerine is a very different process, and it is also not nearly as effective of a solvent as alcohol.
I know people who choose not to have alcohol do so for different reasons, and also have different levels of tolerance for alcohol even being "around." Here are some ideas that may help.
1) If it is something that you do not want in the home, but are tolerant of using in a remedy, you may consider having a friend purchase it and keep the left over in their home.
2) If it is something that can be in the home or you are open to making the remedy, you can simply ONLY use it topically. Echinacea tincture is great for cleaning wounds for example. We keep it in our first aid kit. You can just buy a small bottle of vodka (like a flask size) and keep it around for medicine making.
There really isn’t a substitute for alcohol in tinctures. There are many different ways of preparing herbs whether it is through food, powder (capsules), vinegar, teas or decoctions. Sometimes people want to use vinegar instead of alcohol, however using vinegar to extract herbs instead of alcohol results in an entirely different substance that is not similar to an alcohol tincture. When people tell us they don’t use alcohol we recommend teas instead.
I am not sure if the above ideas meet your needs, but they are all solutions that have worked for others in the past who were also concerned about alcohol.
Now, whatever your choice is about our Kit, just know that tinctures are just one small way herbs can be used. Teas, infusions, decoctions, syrups, salves, lotions, etc... all do not need or use alcohol.
If you want to "skip" the Kit and go to our Herbal Basics course, you can check that out on HerbMentor. It has several lessons (video) that are just as user friendly and basic as the Kit.
