Found a couple of places in the lessons that discussed tannins and alkaloids. There was discussion on what they were and what would happen if they were combined.
It is usually convenient and necessary for home people to store tinctures as simples to be combined later. Many formulas will need to have plants from each category to be combined.
I know that combining dry ingredients prior to tincturing will resolve the chemical conflict. That requires a large investment in materials. Is there a way to mitigate the negative effects when combining simple tinctures that have both tannic and alkaloid properties as simple tinctures?
