Palmath

The palmath is a plant with yellow flowers much sought after by apothecaries, because it allows to recover from all kinds of injuries more quickly. And when a creature is between life and death, a few seconds can make the difference. The subject's breath, on the other hand, becomes horrible for a few minutes.
Giving a dying person an infusion of palmath allows him to stabilize on the second successful death saving throw, instead of the third. On the other hand, it always takes three failures to die.
