Nectar

Nectar is a drink consumed by the Gods. It gives immortality to whoever drinks it. It is closely related to Ambrosia.

Consumption
Nectar is the drink of gods. It is also used for healing by demigods. If a mortal eats it, they would be incinerated. A demigod can eat a little, but taking an overdose could make them feverish. A huge overdose would cause them to incinerate as a mortal would.

When mixed with any kind of alcohole any person will instantly black out after one drink. This will wipe they're memory.
