Manufacturing and Licensing Permits

In Maine, my business is registered as an "herbal craft". I make creams, salves, etc. I can make these from home to sell, no problem. I also make tinctures, however that's a "gray" area because when you make anything for sale to the public that they take internally (and I assume this also includes tea blends), you're supposed to have the health department inspect your kitchen and certify it. To me, for things like tinctures and elixers and even tea blends, this seems like overkill. In fact, many of my fresh herb tinctures are made right on my garden bench outside in the sun. I do have access to an approved kitchen in town and if I really wanted to sell my tinctures on store shelves in town I could take my herbs/alcohol/honey/etc. there. So far I have decided not to do that. Each state has its own regulations and you don't want to get "caught" doing something wrong because it may put you out of business totally.
