Cypress (coriandrum sativum) The French Cypress is a perennial, conical-shaped tree that is about 28 meters (80 feet) high. It is an evergreen with dark green foliage, small flowers and round brown-grey cones with seed nuts inside. The wood is hard and durable, and red-yellow in color. It has many benefits and has been used since ancient times. Its main aromatherapy application is when there has been excessive loss of fluid such as heavy perspiration. The volatile components of this essential oil tend to escape through pores on the skin, eliminating body odor.
