Sweet almond is the seed of the tree Prunus dulcis. People eat it as a nut and press it for its oil. The French name for the tree is amandier.
The nut is a food, high in fat, protein and vitamin E. The oil is used on skin and hair, and as a base for massage blends. Both have a long place in European home care.
Here is the short verdict. Eating almonds has fair human trial support for a small drop in cholesterol. Use on skin is mostly cosmetic, with thin evidence, and long folk use proves neither effect nor safety.
Almonds are rich in unsaturated fat, fibre and plant sterols. In human trials, eating them lowers LDL ("bad") cholesterol by a small amount. That effect is reasonably well shown.
On skin, the oil acts as an emollient (a skin softener). It sits on the surface and slows water loss. Most plant oils behave this way.
In laboratory work, the vitamin E in the oil mops up free radicals. Whether that changes how your skin ages has not been shown in people.
Folk use for earwax rests on a simple idea. Oil softens hardened wax so it shifts more easily.
Sweet almond reaches you in a handful of plain forms.
Whole, flaked or ground nuts, eaten as food
Almond butter, almond milk and marzipan
Almond flour, used in baking
Cold-pressed (virgin) oil, sold for skin, hair and massage
Refined almond oil, used inside creams, soaps and bath oils
Ear drops and wax-softening drops that list almond oil
Food-grade and cosmetic-grade oils are not always the same product. Check the label before you swallow any oil.
Bitter almond oil is a separate item and is not interchangeable with this one. Unrectified bitter almond oil can release cyanide.
Almonds spread through the Mediterranean in ancient times and reached northern Europe by the Middle Ages. Roman and Arab writers both recorded the tree.
Old European apothecaries kept "oil of sweet almonds" on the shelf. It appeared in pharmacopoeias as a base for ointments and liniments.
Folk use was broad. Nurses rubbed it on chapped hands and dry skin. Midwives used it for belly massage in pregnancy, and families dripped it in the ear to soften wax.
The nut itself fed sweet traditions, from marzipan to almond milk during fasting days. None of that history tells you whether it will help you.
Call emergency services at once if you have swelling of the lips, tongue or throat, trouble breathing or swallowing, a spreading rash with faintness, or sudden vomiting after contact. These are signs of a severe allergic reaction.
Stop using the oil and see a doctor if your skin stays red, itchy or sore after a few days.
See a doctor if ear pain, discharge or hearing loss follows ear drops.
Ask your doctor before making almonds a daily habit if you take thyroid tablets, diabetes medicine, or have kidney disease.
In the UK, EU and US, sweet almond is an ordinary food. The oil is sold freely as a cosmetic and as a food oil. Bitter almond oil is controlled, with legal limits on its cyanide-releasing content.
