The caterpillar is like the picture on the feather or more accurately called this thorn is poisonous. This poison thorn works like a syringe. The caterpillar will stick a thorn into an organism that touches or disturbs it by direct contact.
"If the caterpillar (which is usually encountered) is only the surface heat, only itching. But if this is, it is very hot like a fire. That's why it's called a caterpillar," said Hari again.
Itching will last around 3-4 hours. If you feel very disturbing you can take oral antihistamine drugs. Previously, make sure you don't have allergies to antihistamine drugs. If it does not go away or feel anxious immediately go to the doctor.
