Ti tree oil, deadly to reptiles?

[ilovemysnake]

I read that its deadly for reptiles. The wound healing stuff i got for them consists of it.
Was what i read true? its if its deadly, then why would it be in a wound healer?

I was looking at reviews on this product and found the following review-

Because my Malaysian Box Turtle had obvious shell rot about 2 months ago, I ordered this before I went to the vet. Luckily, my vet had already given me a cleaning routine for the shell before I tried to use this stuff; today was the follow up visit, and I brought this along with several other items I had bought for him to take a look at and see what he said.

As soon as he took one look at this, his eyes became big and he asked me if I'd used this yet. I told him no, and he went on to say that Tea Tree oil is toxic to reptiles! He said that Tea Tree oil, topically and especailly internally, is dangerous to all reptiles; he'd had several people who had tried to treat their snakes and geckos with this sort of thing and a few of them had been so severely poisoned they died!
