Biomass production, essential oil yield and composition of Myrica gale L. harvested from wild populations in Scotland and Finland

Myrica gale L. was harvested from wild populations in Scotland and Finland. Above-ground vegetation was assessed for growth and potential yield of biomass. Essential oil yield and composition were measured: leaf oil yield was 0.05–0.29%, flower oil yield 0.97%. Main components were α-pinene [20.1–38.9%], 1,8-cineole [2.5–23.9%], germacrene [0.4–13.2%] and γ-cadinene [8.4–21.0]. The essential oil has a potential use as a midge repellent. Copyright

An investigation into drop sizes of essential oils using different dropper types

Abstract Generally, aromatherapists dispense their essential oils using the dropper-insert, adhering to the theory that 20 drops is equivalent to 1 ml. This article determines that this is very seldom, if ever, the case.
