You will learn very little about making Dit Da Jow at a graduate school for Chinese Medicine. You will learn about the herbs and what they do but not much about dit da jow unless they have a good Dit Da Ke class or department.
You can use glass carboys to store your liniments in. They are 3-6 gallon glass jars that will last lifetimes if properly cared for. You can find them at beer and wine making supply stores.
You do not have to wait 6 months before bottling liniments. Anyone who tells you this is misinformed. You can usually decant from your larger bottle into a smaller portable bottle(many people like Grolsch beer bottles as they are easy to open with one hand) and leave your liniment in the storage container. Most of the time you can decant 6-8 weeks after you have added the alcohol.
A rough grind is good but you can grind finer if you want to. Its all about getting more surface area of the herbs exposed to the solvent(alcohol & water) so that you get more of the active chemicals from the herbs into the solution.
Let me know how I can be of service.
Mouth Boxers have not the testicular nor the spinal fortitude to be known.
Hence they hide rather than be known as adults.
