- Note: Sweet almond should not be confused with bitter almond, which contains amygdalin and can be broken down into the poisonous substance hydrocyanic acid (cyanide).
- The almond is closely related to the peach, apricot, and cherry (all classified as drupes). Unlike the others, however, the outer layer of the almond is not edible. The edible portion of the almond is the seed.
- Sweet almonds are a popular nutritious food. Researchers are especially interested in their level of monounsaturated fats, as these appear to have a beneficial effect on blood lipids.
- Almond oil is widely used in lotions and cosmetics.
These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Early studies in humans and animals report that whole almonds may lower total cholesterol and low-density lipoprotein (LDL/”bad” cholesterol) and raise high-density lipoprotein (HDL/”good” cholesterol”). It is not clear what dose may be safe or effective.
It is unclear whether sweet almond improves anxiety in palliative care patients, but more research investigating sweet almond as the active treatment is needed to make a firm recommendation.
In preliminary study, an ointment made of sweet almond has not shown a benefit when applied to the skin of patients treated with radiation.
*Key to grades:
The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.
Adults (over 18 years old)
- Studies have used 84 to 100 grams of whole almonds daily by mouth with no reported side effects to treat high cholesterol. As a laxative, 30 milliliters of sweet almond oil daily by mouth has been used.
Children (under 18 years old)
- Little information is available for the use of sweet almonds in children, aside from the amounts normally eaten in the diet.
The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.
- Allergies to almonds are common and can lead to severe reactions, including oral allergic syndrome (OAS), swelling of the lips and face, and closure of the throat. People who are allergic to one type of nut may also be allergic to other nuts. Avoid use in anyone with known allergy to almonds, almond products, or other nuts.
Side Effects and Warnings
- In most reports, sweet almond is generally considered to be safe when taken by mouth. Sweet almond may lower blood sugar levels. Caution is advised in patients with diabetes or hypoglycemia and in those taking drugs, herbs, or supplements that affect blood sugar. Serum glucose levels may need to be monitored by a healthcare provider, and medication adjustments may be necessary.
- Sweet almond may have estrogen-like activity. A study in mice reports hair loss and inflammation in the leg joints. There is a report of a fat embolism (fat bubbles traveling through the bloodstream, which is potentially dangerous) due to injection of almond oil into the penis.
- Theoretically, increased intake of almonds (and therefore increased intake of unsaturated fat) can lead to weight gain. However, one study reports that consuming approximately 320 calories of almonds daily for six months does not lead to statistically or biologically significant average changes in body weight and does increase the consumption of unsaturated fats.
Pregnancy and Breastfeeding
- There is little information about the use of sweet almond during pregnancy or breastfeeding. It appears that almonds in regular dietary intake are safe for most non-allergic individuals.
The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.
Interactions with Drugs
- Based on animal studies, sweet almond may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar. Patients taking drugs for diabetes by mouth or insulin should be monitored closely by a qualified healthcare provider. Medication adjustments may be necessary.
- Theoretically, almonds and cholesterol-lowering agents may have additive effects when taken together. Sweet almond may also interact with drugs taken for cardiovascular conditions, fertility, or estrogen activity.
Interactions with Herbs and Dietary Supplements
- Based on animal studies, sweet almond may lower blood sugar levels. Caution is advised when using herbs or supplements that may also lower blood sugar. Blood glucose levels may require monitoring, and doses may need adjustment.
- Theoretically, almonds may add to the effects of herbs or supplements that lower blood cholesterol levels, such as fish oil, garlic, guggul, or niacin.
- Sweet almond may also interact with agents taken for cardiovascular conditions, fertility, or estrogen activity.
Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.
