The pressed seeds produce an oil that is used extensively in the cosmetic business, especially in products for the hair and skin. The oil is yellow and sticky, somewhat like vegetable oil. When a few drops are lightly massaged into the hair and scalp after shampooing, jojoba oil helps cleanse and moisturize the scalp and is helpful whether the scalp is dry or oily. Jojoba also lightly coats the hair, giving it extra shine, body and protection. Jojoba oil makes an excellent conditioning treatment after shampooing with Herbal Shampoo.
New berries appear on mature trees in the fall, and by spring they ripen to blue.
Because the berries take between two to three years to fully ripen, the same plant can have unripe green and ripe blue berries at the same time. In the Middle Ages, juniper's scent was believed to keep the plague away. In addition to their use in herbology, the berries are used as a flavoring agent in gin and luncheon meats. The berries' nutritional profile and volatile oil make them particularly suited to the genitourinary system. They contain vitamin C, among other nutrients.
