Hands-on medicine-making class

Part of the curriculum here at CSCH is to learn professional medicine-making techniques. At the end of the Advanced Herbalism program, we have a week of Herbal Pharmacy where we learn to make tinctures by the old Percolation method – the way the pharmacists used to do back in the 1800s. After working out the math, students in this photo are setting up the first phase where the powdered herbal material (the marc) soaks in the menstruum (which dissolves plant cell walls) to begin releasing the constituents. After a period of time, the material will be packed into percolation cones where additional fluid slowly drips down through it, efficiently collecting constituents on the way. The result is a thorough extraction of the plant material and a potent finished product.
