Respect the medicine. Consider that traditionally medicines that fall to the ground are to be discarded and medicinal herbs should not be placed on the ground. Keep the plant material in clean places.
The cutting board is sacred. Do not to place random items on your cutting board. Generally, a cutting board for herbs should be used only for medicine and not for food preparation. Knives also are best reserved for this special use. At least, you should not cut meats on your medicine-making board, and avoid pungent vegetables. Keep the work area, cutting board, knives, and other tools clean and pure. It is also good to have a pocket knife that is primarily used for harvesting.
