Medi-gel

Medi-gel (medical gel) is an all-purpose medicinal salve combining an anaesthetic and clotting agent used by paramedics, EMTs, and military personnel, produced by the Sirta Foundation. It heals various wounds and ailments, instantly sealing injuries against infection and allowing for rapid healing by having the gel grip tight to flesh until subjected to a frequency of ultrasound. It is sealable against liquids - most notably blood - as well as contaminants and gases. Technically its properties make it illegal under genetic modification laws, but the restriction, in this case, is ignored because of the product's beneficial properties.

Medi-gel can be gained from looting or as a reward from NPCs. It can also be replenished from aid stations, from the SSV Normandy's medical bay, at the Med Clinic on the Citadel, or (if available) the apartment on Intai'sei. At various shops one can purchase upgrades that allow more medi-gel to be carried (up to 10 units).

Using medi-gel involves a 60 second cooldown period which can be shortened with high-grade omni-tools and / or the Medicine talent. It heals all wounded squad members for a base of 40 health. The amount of health restored on medi-gel can be increased with the First Aid talent, and the Medic specialization allows medi-gel to revive fallen squad members.

In Mass Effect 2, Medi-gel is no longer used in the exact same way. A new self-healing system (see Codex "Body Armor" entry), managed by your armor suit microframe computers, automatically uses small quantities of it when required in order to slowly regenerate your squad members health, as long as they are not taking damage. Massive doses (corresponding to the Medi-gel units you can hold - up to 8 - and retrieve from packs or medical stations) can be injected through the new Unity power, serving the purpose of quick healing or reviving squadmates.
