CTFA Name: Prunus Amygdalus Dulcis
The almond tree grows to 23 feet and blooms with hundreds of white flowers in early spring.1 The leathery skinned inedible fruit contains the almond seed (nut) at its center.2 The tree is native to North Africa, Western Asia, and the Mediterranean and is now also found in North America, the Middle East, and Australia.1,3 Sweet almonds should not be confused with bitter almonds which have a toxic component and are inedible.2
The oldest written account of almond cultivation is in the Bible. Aaron’s rod was made of almond wood that surprisingly bore white flowers and fruit.1 In Greece, guests are given uneven numbers of almonds at christenings, weddings, and the ordinations of priests for good fortune and happiness.3
Historically, the whole almond nut was used as a folk remedy to relieve heartburn.4 More recently, almond oil has been used externally for its cleansing and protective properties for the skin.3
The varied content of fat, carbohydrate, and protein along with many other nutrients, makes almonds a common food of choice when weight gain is desired. When taken orally, almond oil is easily digested and absorbed. It is absorbed through the skin more slowly. The cosmetic industry has found that both almond oil and almond meal tend to not irritate the skin, making them appropriate for cosmetic and skin care products. Products containing almond include lotions, creams, makeup, skin cleansers, and suntan lotions.2
