How can i make an herbal extract in a form of powder?
Answer: Through evaporation. Let's say your herbal is a tea that needs to be steeped within water and then drunk. Prepare the tea as mundane. Then take it and put it in a container and put it under very low flame on the stove. Don't tolerate it boil, just keep it at the warmth you would very hot tea. After awhile, all the marine will boil away. Scrape off the residue in the pot (it help if it is a not stick pan) and put this in a coffee grinder. Presto.powdered herbs, primed for gelcaps..
You will need some kind of grinder, approaching a coffee or nut grinder, which will do fine grinding, then you can buy empty capsule from any good herbalists & pack the powder into these & take them close to a pill.
Be sure that the herbs in interrogate don't need to be infused or decocted though.
