Macadamia, (genus Macadamia), genus of four species of evergreen trees belonging to the family Proteaceae known for their richly flavoured edible seeds. The trees originated in the coastal rainforests and scrubs of what is now Queensland in northeastern Australia and are grown commercially in a number of subtropical areas. Commonly known as macadamia nuts, the seeds are often roasted and salted or are used by bakers and chocolatiers in confections and chocolates. They are a good source of calcium, phosphorus, iron, and vitamin B, and they contain 73 percent fat.
Macadamia integrifolia, commonly called macadamia nut, is a large, spreading broadleaf evergreen tree that typically grows to 30-50' tall. It is native to rainforests in southeastern Queensland, Australia. Macadamia nuts were a food source for aborigines long before Europeans first visited Australia. This tree was first introduced to Hawaii in 1837. Glossy oblong-lanceolate to oblong-ovate leaves (to 8-10" long) usually in whorls of three have slightly wavy margins. Sweetly fragrant, white to pinkish-white flowers (each to 1/2" long) in narrow drooping axillary racemes (to 8" long) bloom in winter and spring. Flowers are followed by the nuts. Each creamy white nut is encased in a hard, smooth, shiny shell. Shells are so hard that they cannot be opened by hand nutcrackers. Commercial fruits are opened by powerful husking machines. Although macadamia is native to Australia, Hawaii generally receives credit for developing the macadamia nut industry. Two species of macadamia nuts are commercially grown today: M. integrifolia (smooth-shell type) and M. teteraphylla (rough-shell type). Nuts commercially produced in Hawaii are from M. integrifolia which is by far the most commonly cultivated type. No other U.S. State has any significant commercial production, with the possible exception of California. Nuts produced in California are rough-shell types (M. tetraphylla).
Essential oils are distilled from the aromatic leaves, bark, and roots of plants. If applied to the skin directly, they can cause reactions, such as severe irritation, redness or burning.
Carrier oils and essential oils are made from plants. Carrier oils are used to dilute essential oils and “carry” them to skin. That’s because essential oils are potent and can cause irritation when applied directly to skin. Most carrier oils are unscented or lightly scented and don’t interfere with an essential oil’s therapeutic properties. They may be used alone or with other oils to nourish skin.
Carrier oils are used to dilute the essential oils and help “carry” them into the skin. Aloe vera gels and unscented body lotion are also sometimes used as carriers.
To be used in aromatherapy, it is recommended that the oil is obtained through cold pressing. In this process, the oil is extracted by crushing the plants. Users claim that the fragile nutrients in the oil can be damaged if they are extracted with heat. Venkatramna’s carrier Oils are extracted from the Cold Pressed method to retain their properties.
