It's part of my cold-care formula. Sometimes I don't have any, because I make the extract from the fresh flower buds and I have to grow them myself (second year - first year is just leaves). Fascinating very sticky/resin-y buds. I should look it up again - pretty sure it contributes to the lung tonic / expectorant part of the formula. Interesting aromatic scent.
