I grow Mexican Marigold and other herbs alongside my veggies-it is not menthol-it has a Tarragon flavor-Tarragon does not grow all that well here-the Mexican Marigold does-I use it fresh fresh in any dish that calls for Tarragon-especially good with fresh green beans...
Not menthol-menthol (to paraphrase Whoopi-Whoopi) but the same function as menthol, to lower the harshness of the tobacco smoke.
Still, good to know, I may try growing some here in the high desert.
