I Dream In Soap has a newer video on her Christmas Pudding soap. I just watched it the other day, and she gives a little information on the more irritating EOs. Shes in the UK, and their usage rates are regulated (quite moreso than the US from what I understand).
With that said, I have enjoyed EOs for many years and have done a lot of reading on them. I wouldnt dream of putting cinnamon oil on my skin, but you can apply clove oil on a sore tooth/gums to numb it. Its actually what the dentists use to disinfect a tooth before filling it, or use to anyway.
I honestly know nothing about allspice. But
@DeeAnna gave you good info for that.
I would love to use more essential oils in my soaps, but i tend to stick to the safer oils that can be used neat like lavender and tea tree. Spicier oils are a little more iffy, especially if you are giving the soaps to other ppl to use. There is so much to know about essential oils that you should really study them before adding them to your soap.
People love Bergamot. Due to citrus oils (particularly bergamot) being photosensitizing for your skin, i wouldnt use it in soap.
Chamomile can cause an allergic reaction in ppl allergic to ragweed...pine tar can cause a reaction in ppl allergic to xmas trees lol (inside joke).
I have yet to use an EO calc, cause i am not sure about the real safe usages in soap...so i mostly dont use them. My best guess would be to dilute with your batch oils accordingly in essential oils that are skin safe. Most spicy oils are not, at least without proper knowledge first.
