Scientific Name: Almond Who is this for?
Uses
Note: Bitter almonds are different from the "sweet" almonds sold in the United States. Generally, bitter almonds should not be taken by mouth. For centuries, sweet almonds have been used as food by humans, animals, and birds. They contain protein, fiber, unsaturated fat, and minerals such as calcium and magnesium. Fats are generally classified as saturated or unsaturated according to their chemical structures. Usually solid at room temperature, saturated fats mainly are derived from animal sources. Saturated fats are more likely to form deposits in blood vessels, thereby increasing the chance of having high cholesterol, heart disease, and other conditions. Liquid plant oils such as sweet almond oil, are mostly unsaturated. They are less likely to accumulate in blood vessels. Although they contain unsaturated fats, most edible nuts, including sweet almonds, have a high fat content--making them quite high in calories, as well. In general, nuts have not been recommended for general consumption as a regular part of the diet. However, several human and animal studies that were conducted in the last few years have found that replacing animal fat in the diet with either sweet almonds or sweet almond oil produced reductions in three "bad" cholesterol levels--total cholesterol, low-density lipoproteins (LDL), and triglycerides. In addition, levels of high-density lipoproteins (HDL), the "good" cholesterol remained relatively constant. Partly due to these results, in 2003, the U.S. Food and Drug Administration (FDA) allowed packages of sweet almonds and other nuts to begin carrying a modified health claim: "Scientific evidence suggests but does not prove that eating 1.5 ounces per day of most nuts, such as almonds, as part of a diet low in saturated fat and cholesterol may reduce the risk of heart disease." Sweet almond oil is used topically to moisturize dry skin, soothe chapped lips, and relieve itching due to dryness. Because sweet almond oil is not greasy, it is absorbed quickly. An especially mild oil, it generally does not irritate skin and it does not appear to cause sensitization that may lead to allergic reactions. Occasionally, sweet almond oil is taken by mouth for a mild laxative effect. When should I be careful taking it?Bitter almonds should not be eaten. Children under the age of 12 should not take sweet almond oil by mouth due to the slight possibility that they could breathe particles of the oil into their lungs. Precautions
Women who are pregnant or breast-feeding should avoid taking sweet almond oil by mouth because not enough is known about how it might affect a developing fetus or an infant. Individuals who have allergies to peanuts or other types of nuts may also be sensitive to almonds. In one very small study, almond pollen produced allergic responses in a significant percentage of participants who were allergic to grass pollen. Rarely and mainly in Asia, cases of food poisoning have been associated with eating raw sweet almonds. Commercially grown almonds usually are treated to destroy salmonella and other bacteria that may cause food poisoning, however. What side effects should I watch for?
No side effects have been reported from eating sweet almonds in moderation. Taking sweet almond oil by mouth may result in oily leakage from the digestive tract. What interactions should I watch for?
No interactions have been reported between sweet almonds or sweet almond oil and prescription drugs, non-prescription drugs, herbal products, or foods. However, taking any oil by mouth possibly may interfere with the absorption of drugs or fat-soluble vitamins. To minimize possible interference, sweet almond oil should be taken at bedtime, at least 2 hours after eating or taking medications. Some interactions between herbal products and medications can be more severe than others. The best way for you to avoid harmful interactions is to tell your doctor and/or pharmacist what medications you are currently taking, including any over-the-counter products, vitamins, and herbals.

Should I take it? Believed to have originated in the area around the Mediterranean Sea, almond trees grow wild in most dry, hot regions. They are cultivated in China, Greece, Italy, Spain, and most countries of the Middle East. The interior valleys of California, however, now supply approximately 75% of the commercially-produced almonds used in the world. Almonds grow on fairly small trees that frequently are planted in orchards. A member of the rose family of plants, almond trees flower early in the year--producing white or pale pink blooms that look like wild roses. Leaves appear after the flowers. Green or red fruits develop in early or mid-summer, depending on the region and the type of almond. Almond fruits resemble small apricots, but the soft part cannot be eaten. The fruit dries to a thin, tough skin that eventually breaks open to reveal the nuts, which are covered with distinctive spongy outer shells that surround thin, hard inner shells. Two major types of almonds are grown commercially. Sweet almond (Prunus amygdalus dulcis), the one most familiar to Americans, is the almond used for food. While sweet almonds may be eaten alone, they are also widely used in bakery, candies, and cooking. They may be blanched (the dark skins removed), ground, and substituted for wheat flour or mixed with water to form a substitute for milk, usually called "almond milk". In Europe and North America, almond paste--a thick combination of finely ground blanched sweet almonds, sugar, and a thickener such as glycerin or egg whites--is often used to make cake decorations and a molded candy called marzipan. A coarser grind produces almond butter, which is similar to peanut butter. Sweet almonds are also included in nougat and other candy. The second main almond type is bitter almonds (Prunus amygdalus amara). Generally shorter and wider than sweet almonds, bitter almonds grow under the same conditions as sweet almonds. However, because bitter almonds are considered to be a controlled substance in the United States, growing or selling them is illegal in this country. Unlike sweet almonds, bitter almonds cannot be eaten raw since unprocessed bitter almonds contain a poison called hydrocyanic acid, prussic acid, or cyanide. They must be heated to remove the dangerous substances. Once they are processed, bitter almonds are used to make flavorings and fragrances. Although bitter almonds may be used in some countries to treat serious illnesses, no scientific evidence shows that they are either effective or safe to take by mouth. Cases of cyanide poisoning are not very common, but deaths have been reported--especially among children--after eating unprocessed bitter almonds. Sweet almond oil is a fixed oil--meaning it does not evaporate and does not have an odor. It is obtained by pressing a combination of sweet almonds and bitter almonds. To differentiate it from the volatile oil obtained from bitter almonds, fixed almond oil is nearly always called "sweet almond oil". Volatile oils evaporate easily at room temperature and they often have a characteristic smell. In addition to its oral and topical uses in herbal medicine, sweet almond oil is used in the pharmaceutical industry as a carrier for injectable drugs that deteriorate in a water-based carrier. Sweet almond oil is also used as massage oil and as an ingredient in cosmetics. Sometimes, chopped almonds of either type or ground almond shells are used for soap in parts of the Middle East. Almonds or almond oils may be added to conventional soap products for fragrance and moisture. The spongy outer hulls of almonds may be ground and used to feed cattle or horses. Dosage and Administration
In studies, the amount of sweet almonds eaten by participants varied from about an ounce per day to about 3 ounces per day. However, sweet almonds and/or sweet almond oil were not added to the regular diet. Instead, they replaced some of the more fatty foods (such as meats and dairy products) that would have been eaten instead. One ounce of almonds (about 20 almonds) contains about 175 calories, and one tablespoon of almond oil has about 120 calories. By mouth, a typical dose of sweet almond oil for laxative purposes is up to 2 tablespoons once a day. It should be used only long enough to produce a soft stool. In general, laxatives should not be taken for longer than one week at a time. When applied to the skin, sweet almond oil may be used as many times a day as it is needed and no limits are placed on the amount to use at one time. Sweet almond oil may become rancid fairly quickly; however, so it should be purchased in small amounts and stored in a cool place. Summary Sweet almonds may be eaten in place of fatty foods to help lower cholesterol levels. In medicine, sweet almond oil is used mainly as a moisturizer for the skin although small amounts may be taken by mouth as a laxative. Risks Children, pregnant women, and breast-feeding women should avoid taking sweet almond oil by mouth. Bitter almonds contain toxic substances and unprocessed sweet almonds may be contaminated with bacteria that cause food poisoning. Side Effects Taking sweet almond oil by mouth may result in an oily discharge from the rectum. Interactions Although sweet almond oil may interfere with the absorption of drugs or vitamins, neither almonds nor sweet almond oil has been associated with any interactions.
