Mega-Health
From Quake Wiki
A megahealth gives you 100 extra points of health. You have a maximum of 250 health points, so you can actually pick up a couple of these things. After a short grace period, any extra health you have wears off at a rate of about 1 point per second until it reaches the standard maximum of 100.
