使用
cedarwood oil (Thuja occidentalis)(cedar; thuja) is credited with an tiseptic, sedative, and astringent properties. It is used as a fixative in fragrances because it blends well with other oils. This clear oil C is also valuable for use on skin eruptions and to relieve itching. It is good for acne and oily skin, and could be helpful in cases of dermatitis, eczema, and psoriasis. Two types of cedarwood oil exist: Atlas cedarwood oil from Morocco (Cedrus atlantica) and one derived from the Juniperus virginiana (or red cedar) that is a juniper of the united States (its oil, however, is very similar to true cedarwood). The oil may cause skin irritation when used in high concentrations. Cedarwood oil is obtained from recently dried, leafy, young twigs.
