Nardyll

Description
Nardyll is an anti-depressant, an irreversible MAO inhibitor, that is rarely used because of its strength and its plethora of interactions with other drugs. There are no known recreational uses. It is made by Jamison Family Pharmaceuticals. Bottles of it were found on the forest floor the day after Sam Duncan disappeared, and were also found in Sam's body when he died, according to his autopsy.

The Hallucinogenic Gas found in the Deepriver Forest is similar to DMT, which negatively interacts with the ingredients found in Nardyll.
