I basically follow the package instructions - depending on brand and strength of carvacrol ( active compound).

I take a few drops under the tongue at symptom onset. Maintenance daily as needed until symptoms are gone. Not for the faint of heart though. This stuff can be very hot - don’t let it hit your taste buds.

Gel caps are available too if you don’t like the sublingual.

I like the Zaino brand w/ cinnamon.
