I have used both the soak and wait method and Master Wu's recipe with great success. I understand the desire to not touch alcohol (I didn't drink for 16 yrs). But with a well made tincture the alcohol is just a medium for the intoxicant, not the intoxicant itself.
Let us know how your glycerin experiments go and I'll post when I get some coconut oil. Should I be able to get that at a health food store? My local grocery doesn't carry it.
