You can use your medical knowledge to quell an upset stomach and overcome otherwise debilitating effects.

Prerequisite: Heal 5 ranks.

Benefit: You can use the Heal skill to attempt to negate the sickened and nauseated conditions. This is a standard action, and requires 1 use from a healing kit. If successful, the target is immediately cured of the sickened or nauseated conditions for 1 hour. If the cause of the sickness or nausea is gone by that time (such as, for example, if its duration was only one minute), it remains cured. This treatment does not in any way protect the target from further sickness or nausea, and he can become sickened or nauseated again during that hour. The DC to cure sickness is 20, and the DC to cure nausea is 25.
