I am also wondering about shelf life. I made a salve from the course (calendula and lavender healing salve – so I adjusted it a bit from the recipe in the course), both with a cold infusion method for the oil infusion (so from dried herbs). I used beeswax and it was avocado oil…so the shelf life? I made it in June and it still seems fine as I use it! We have passed the 3 month mark. Is it fully ok past that? I don’t see or smell any problems with the oil. Is use within 6 mths recommended or is it totally dependent on the storage and use of it? If I ended up gifting items at the holidays, what can I tell my giftees for length of use?
