Here's my first foray into this area. I prepared a tincture of 50 ml water and 5 drops of Cypress, Cupressus sempervirens EO. The brand is Aromaforce. I have this in a ceramic simmering potpourri with a tea light.
This is a green, slightly resinous, foresty and also highly medicinal sort of scent. Like a pleasant sort of lineament. Not woody at all.
