Hi Danica,
Thank you for pointing out that the Assignment and Submissions page still includes Herbal Body Products and Gift making as an assignment. You no longer need to submit this assignment, just one for External Medicine making.
As for hydrosols, I personally am in Nova Scotia and have a couple of connections here and I am fairly sure they ship. One is https://www.robertsonsfarm.com/products/hydrosols

As for how much shelf life vitamin E-Tocopheral adds, I can’t say I know and finding that information out seems unclear. I imagine that it adds a few months to 6 months on to the existing shelf stability. It works by significantly slowing oxidation of a product/fat/oil.
With warmth,
Benna
