Question.
I know that we can make herbal healing creams, such as a Calendula cream, using calendula-infused sesame oil, Shea Butter, Distilled Water or Hydrosol, emulsifying wax, vitamin E, and a natural preservative.
However, I have seen Calendula creams on the market that use Calendula Tincture, so that for every 1g of cream, you're getting the equivalent of 20mg of dried Calendula flower.
How much Calendula tincture would you need to add to a very thick base cream to get a therapeutic dose of 20mg/g equivalent of dry calendula flower?
Asking, as there are times when I need Calendula cream, but I am out of it as well as the infused oil, but I always have the tincture in stock.
