I can assure everyone here that this is a safe method. I rescued a BCI that was underweight and had a very severe case of RI. I found a really respected vet to take him to. The vet put him on Batryl. The vet told me to use vicks vapor rub and eucalyptus oil if the batryl did not work. The batryl did not work so I started the at home treatment. After 2 treatments and the injections I took him back to the vet because I thought I was still seeing symptoms of RI. The vet told me that the boa was 100% healthy and that there was no sign of RI anymore. However he has 2 of the symptoms of RI but he does not have the infection anymore. All you need is 2 storage containers, boiling water, 1tsp of vicks, and 6 drops of eucalyptus oil. The magic cure. However a snake should still be going to the vet to be checked FIRST.
