I sometimes use Ravensara if I feel a cold sore coming on on my lip. In the past, I used jojoba as the carrier.

After reading your latest blog info, I made a 5% Ravensara using Tamanu as the carrier oil for topical use. Would it be safe for me to use this combination on my lip, too? Is it safe to injest minor amounts of Tamanu?

I frequently apply to my lips -- there's no harm in ingesting a little bit. I have yet to hear of ingestion of larger quantities, despite all the resent research I've looked into (see the Tamanu science update blog post if you haven't yet).

With all those positive aspects, I can't see it being unhealthy, but this is still a guess. It might not taste so hot. There doesn't seem to be mention anywhere of any components that pose health risks -- if anyone is aware of any, we'd be happy to hear!
