La tossina della medusa è “tremolabile” (viene neutralizzata dal calore), si possono pertanto ottenere buoni risultati applicando del calore (come con le pietre riscaldate dal sole stando attenti che non ustionino) sulle lesioni cutanee.

FIRST AID
Stab wounds should be washed with cold sea or fresh water. It is recommendable to
perform a cross incision on the wound and suck the poison out. In the case of
wounding by certain species that carry thermolabile poison (Trygonidae) it is
recommendable to put the wounded part of the body into hot water. In the case of
ingestion of poisonous fish flesh the poisoned should be brought to a hospital as soon
as possible.

The venom delivered is variable in toxicity among types of lionfishes. However, in all species the venom produced is comprised of thermolabile proteins which, as the name suggests, are sensitive to heat.
