Common Name: Sweet Almond, Sweet Almond Oil

Scientific Name: Prunus amygdalus var. dulcis (Borkh. ex DC.) Koehne

History and Origin

The almond tree is a species that belongs to the Prunus genus and the Rosaceae family. The almond kernel has been used as a nutrient-dense food for mankind.

Apparently, it originated from one or more wild species that evolved in the deserts and mountain slopes of central and southwestern Asia. Almonds were among the first plants to be domesticated. The earliest archaeological evidence suggests that this occurred in Jordan. Almonds are the most important nut in the world in terms of commercial production. ⁽¹⁾

Almonds are considered worldwide to be the most pleasant and consumed tree nut, with applications in the food, cosmetic, and pharmaceutical industries. ⁽²⁾ Likewise, the demand for almond oil is on the rise globally due to the oil’s health benefits and high nutritional value. The rise in demand for aromatherapy products and the growing use of almond oil in cosmetic formulations, which is due to an increase in preferences for natural ingredients, are the primary factors that drive the global almond oil market. ⁽¹⁾

The production of almonds has increased dramatically globally during the last ten years, according to the Food and Agriculture Organization (FAO). ⁽²⁾ The United States, Spain, and Australia are the top producers, followed by Iran, Morocco, Italy, Syria, Turkey, and Tunisia. ⁽¹⁾

Wet climates are not suitable for growing almonds because of their sensitivity to moisture. This tree prefers a Mediterranean climate, and it is often cultivated in the temperate zone. ⁽³⁾ Almond is grown in the whole Mediterranean region, in California, in northwest Mexico, in a small part of Australia, and in other areas around the world. ⁽¹⁾

Sweet Almond Plant Structure

Almonds are deciduous trees or shrubs of varying size and shape ⁽²⁾with mildly red-tinged branches, thorny in their wild form but not in their cultivated form. The leaves are glabrous, oblong-lanceolate-acuminate or serrate, tough, glossy, and dark green. The flowers are pale pink or white. The ripe fruit is the medicinal part. The fruit is oblong-ovoid, compressed, gray-green, and velvety-downy. The nut shell is hard and compressed. The seed is cinnamon brown and 2 cm long by 1.2 to 1.5 cm wide. ⁽⁴⁾

Almond has considerable genetic variability around the world. Based on taste, two major varieties were identified: the bitter almond (“amara” variety) and the sweet almond (“dulcis” variety). Almonds are characterized as sweet or bitter, depending on the amount of amygdalin in the kernel. ⁽²⁾ The fixed sweet almond oil comes exclusively from edible almonds (Prunus amygdalus var. dulcis). Sweet almond oil is a pale-yellow liquid with a nutty taste.

Fresh sweet almond oil, extracted using pressing, shows low contents of free fatty acids, peroxides, and phosphatides, and therefore it can be consumed directly and used for culinary purposes (mainly as a salad dressing and vegetable dips) without refining as a 100% virgin product. ⁽¹⁾

What Are Sweet Almond Oil Side Effects?

- When taken by mouth: Sweet almonds are often ingested orally as food. To determine whether sweet almonds are safe to use as medication, there is insufficient trustworthy information available. ⁽²¹⁾

- When applied to the skin: Sweet almond oil is suitable and safe for any skin type. ⁽¹⁾If you have acne-prone skin, check with your healthcare provider before applying this oil directly to your face.⁽²²⁾

Irritable bowel syndrome (IBS): Consuming excessive quantities of sweet almond oil may worsen diarrhea and pain in patients with IBS.⁽²¹⁾

- Pregnancy and breast-feeding: Please discuss the benefits and risks with your healthcare provider before taking sweet almond oil. ⁽²³⁾

- Diabetes: Some people may have a decrease in blood sugar after eating sweet almonds. Keep an eye out for symptoms of hypoglycemia, use sweet almonds, and closely check your blood sugar if you have diabetes.

- Surgery: In some cases, sweet almonds may reduce blood sugar. Theoretically, blood sugar regulation both during and after surgery may be impacted by sweet almonds. At least two weeks before a planned operation, stop consuming sweet almonds. ⁽²⁴⁾

- Allergy to almond oil: The oral and topical use of sweet almond oil is generally safe for people. Anyone who has a severe nut allergy should not use the oil topically (on their hair and skin) or orally because it may cause a serious allergic response. ⁽²⁴⁾

Generally, every person may be allergic to certain herbs and spices. This sensitivity must first be diagnosed by the person and, secondarily, by the physician. However, these allergic reactions do not cause chronic or acute side effects, and after identifying the allergenic plant and removing it from the diet, allergy-related complications will be eliminated. No company or product can be aware of the allergic reactions of different bodies in advance. The body's incompatibility with one or more specific herbs rarely occurs, but consumers may encounter it anyway.

Sweet Almond Oil Health Benefits

1. Relieving Constipation

In 2022, the effects of abdominal massage and oral administration of sweet almond oil on constipation were studied in elderly people.

For two weeks, the oral consumption group received 9 ml of sweet almond oil orally every twelve hours (i.e., 18 ml per day). There were seven sessions conducted every other day. Patients in the abdominal massage group received 15 minutes of abdominal massage with 18 ml of sweet almond oil at specific times (8–11 a.m.). Over the course of two weeks, seven sessions, one every other day, were conducted to accomplish this.

The results of this study showed that abdominal massage with sweet almond oil and its oral administration are effective in treating constipation and improving the quality of life among elderly individuals. ⁽⁵⁾

Also, according to a 2019 study on the constipation model of mice, the oral administration of sweet almond oil has laxative activity. ⁽⁶⁾ This noninvasive, simple, and affordable approach is advised to be used to reduce constipation because of its high prevalence and detrimental consequences on quality of life and other health indicators.⁽⁵⁾

2. Preventing Skin Aging and Repairing Damaged Skin

The sweet almond oil has moisturizing, softening, anti-inflammatory, and anti-aging properties ⁽⁷⁾ and has significant levels of vitamins E and K, which maintain elasticity and aid in skin regeneration ⁽¹⁾, keeping the skin smooth and supple ⁽⁷⁾. For these reasons, the oil is often used in skin and hair care products.

Since it is suitable for all skin types and is simple to absorb by the skin, ⁽⁷⁾ almond oil is one of the most widely used oils in aromatherapy and massage therapy. ⁽¹⁾

Sweet almond oil reduces skin damage associated with exposure to UV radiation.The results of a study on mice showed that topical almond oil could prevent the UV-induced structural damage, and it was also shown to be helpful in slowing down the photoaging process. ^{(2, 8)}

Sweet almond oil prevents the itching of striae and their progression during pregnancy. The results of a study on nulliparous women showed that topical application of sweet almond oil during pregnancy prevents the spread of striae on the surface of the abdomen and relieves the itching and erythema. ⁽⁹⁾

This very nutritious oil is particularly good at treating dry, brittle nails. ⁽¹⁰⁾

3. Strengthening Hair

Due to its light texture and ease of penetration deep into the skin, sweet almond oil helps to unclog hair follicles and clear the scalp. It is also a gentle moisturizer and conditioner for hair, repairing damaged and dry hair and restoring it to its original luster and shine. ⁽⁷⁾

4. Anti-cancer

According to a 2022 study, consumption of sweet almond oil can prevent cancer. This oil can significantly reduce new blood vessel growth in tumors; thus, it is useful for inhibiting tumor growth and metastasis, too. ⁽¹¹⁾

In addition, several studies have proven that consumption of sweet almond oil can reduce colon cancer risk. ^{(2, 12)}

It is interesting to note that cancer patients' quality of life is significantly improved by almond oil massage. Cancer patients who use sweet almond oil aromatherapy report feeling less depressed, anxious, stressed, and fatigued, as well as getting better sleep. ⁽²⁾

5. Increasing Fertility

Sweet almond oil showed protection against sperm damage. ⁽²⁾ According to a 2015 study on diabetic rats, adding sweet almond oil to the diet is beneficial for raising the percentage of live, motile, healthy morphology, and count of sperm. ⁽¹³⁾ The antioxidant content of the sweet almond oil is thought to be the cause of this effect. ⁽²⁾

6. Reducing Appetite

According to the results of a 2019 study, sweet almond supplementation with an exercise training program can reduce appetite and help overweight women lose weight. Also, the researchers suggested that the presence of fatty acids, like linoleic acid (omega-6) in the almond and its oil, reduces the absorption and synthesis of fat. ⁽¹⁴⁾

7. Antidepressant Properties

In 2018, the anti-depressant effect of oral administration of sweet almond oil, along with the inhalation of lavender essential oil, for alleviating depression was studied in rats. Based on the results, although either consumption of sweet almond oil or lavender essential oil aromatherapy had an antidepressant impact, the combined treatment (lavender oil inhalation and almond oil application) resulted in an additive effect. This implies that a treatment with sweet almond oil, inhalation of lavender essential oil, or a combination of both may improve the hippocampus area of the brain's functionality. ⁽¹²⁾

8. Regulating Blood Fat Levels

The fatty acid composition of almond oil has dietary importance. Although almonds contain high amounts of fat, the oil does not contribute to cholesterol formation in humans since monounsaturated and polyunsaturated fatty acids (MUFAs and PUFAs) are abundant in almond oil that lower blood levels of total cholesterol and LDL cholesterol (bad cholesterol). ⁽⁷⁾

A 2002 study showed that sweet almond oil consumption lowered both total and LDL cholesterol levels while increasing HDL cholesterol (good cholesterol) too. ⁽¹⁵⁾

9. Regulating Blood Glucose Levels

In a 2019 study, the effect of co-ingestion of sweet almond oil with a high-carbohydrate meal on controlling postprandial glycaemia was evaluated in mice. The results showed that sweet almond oil had a postprandial glycaemia-lowering effect without changing the insulin level.

Sweet almond oil in the carbohydrate meal could slow gastric emptying because of its high energy content and medium viscosity, and the researchers suggested that its glycaemia-lowering effect could relate to the gastric emptying rate. ⁽¹⁶⁾

In addition, a 2011 study on impaired glucose-tolerant people found that participants who consumed almond oil with their breakfast meal had lower blood sugar levels, both after the meal and throughout the day, compared to participants who did not. ^{(7, 17)}

10. Improving Liver Function

In a 2011 study, the hepatoprotective effects of sweet almond oil against acute liver injury were evaluated in rats. It was demonstrated that sweet almond oil is useful for the treatment and prevention of liver damage and chemical-induced hepatotoxicity.

According to the researchers, the hepatoprotective effects of almond oil may be due to its unsaturated fatty acids, tocopherols, and phenolic compounds. The suppression of lipid peroxidation pathways and the increased activity of antioxidant enzymes are two of the protective strategies. ⁽¹⁸⁾

11. Improving Cardiovascular System Function

Consuming sweet almond oil may protect against cardiovascular disease, at least in part, by modifying blood lipid levels, according to all human clinical research. Sweet almond oil supplementation significantly reduces the plasma levels of total cholesterol, LDL cholesterol, and triglycerides as well as significantly increases HDL cholesterol levels, which improve dyslipidemia and prevent cardiovascular disease. ⁽²⁾

12. Increasing Antioxidant Activity

Almond is one of the best sources among other nuts in terms of vitamin E, which is a soluble lipid antioxidant. ⁽¹⁹⁾ According to a 2019 study, sweet almond oil possesses antioxidant properties, and researchers recommend its use as a dietary antioxidant. ⁽²⁰⁾

Nutritional Information

The primary nutritional components of almonds are lipids, which consist of a variety of fatty acids, including SFAs, MUFAs, and PUFAs, as well as oil-soluble substances, including squalene, phytosterols, tocopherols, and tocotrienols. ⁽²⁾

Sweet Almond Oil Daily Dosage

Take one to two tablespoons (15 to 30 ml) per day directly or add it to a food, salad, or beverage.

Bioactive Compounds

Fatty acids: Only 8% of the fatty acids in almond oil are saturated fats (palmitic acid and stearic acid ⁽²⁵⁾), while it is high in monounsaturated fats. ⁽¹⁾ Oleic acid (omega-9) and linoleic acid (omega-6) are the most important unsaturated fatty acids found in almond oil. ⁽⁷⁾

* Oleic acid, which makes up between 50 and 70 percent of the total fatty acid content of almond oil, is the main fatty acid. ⁽¹⁾

Phytosterols: Almond oil was found to have an important amount of phytosterol content. β-sitosterol is identified as the major phytosterol in almond oil. ⁽²⁾

Tocopherols and tocotrienols:Vegetable oils are the major sources of vitamin E, which includes tocopherols (α-, β-, γ-, and δ-tocopherol) and tocotrienols (α-, β-, γ-, and δ-tocotrienols)—that also have antioxidant properties. ⁽²⁾ Sweet almond oil contains large amounts of vitamin E, ⁽¹⁾ especially α-tocopherol, which is the most biologically active form of vitamin E. ⁽⁷⁾

Best Time to Consume

Basically, you can consume sweet almond oil any time of the day. The best time depends on why you are using the oil. For example:

- To control blood sugar levels: According to a study, consuming a breakfast with added sweet almond oil had lower blood sugar levels both after the meal and throughout the day. ⁽⁷⁾

- To relieve scalp itching and flaking: Massage sweet almond oil into your scalp and let it sit for at least an hour before a bath. ⁽²⁶⁾

- To strengthen your hair: Apply sweet almond oil to your hair a few hours before you wash it and let it sit on your scalp. ⁽²⁷⁾

- For constipation: Take sweet almond oil with moderately warm milk at bedtime.

Possible Drug Interactions

Medications for Diabetes (Antidiabetes Drugs): Sweet almonds may help some individuals reduce their levels of blood sugar. Additionally, blood sugar levels can be lowered using diabetes medication. Taking sweet almonds with diabetic medication may cause your blood sugar to drop dangerously low. Pay close attention to your blood sugar levels. You may need to change the dose of your diabetes medication. Among the medications used to treat diabetes are glimepiride (Amaryl), insulin, rosiglitazone (Avandia), glyburide (DiaBeta, Glynase PresTab, Micronase), glipizide (Glucotrol), tolbutamide (Orinase), pioglitazone (Actos), and others. ⁽²⁴⁾

Traditional Use

Almond is used as an emollient, lithontryptic, demulcent, diuretic, carminative, astringent, laxative, and tonic in traditional medicine. Almond is a traditional cure for ulcers and heartburn.

The kernels are added to the diet to prevent peptic ulcers. ⁽³⁾

The ancient Greek doctors Hippocrates and Galen described almonds as "hot" and noted their "heating," "cleansing," "nourishing,” and “strengthening mental function” properties. ⁽¹⁾

Sweet almond oil is used to flavor baked foods and perfumes. ⁽³⁾

Also, the oil had been used traditionally to treat dry skin conditions such as psoriasis and eczema. ⁽²⁸⁾ The ancient Romans used sweet almond oil extensively in skincare products. Sweet almond oil was also embraced as a beautifier in Europe as early as the 16th century. ⁽³⁾ Massage therapists have been using this oil, which many believe to be an excellent emollient, to lubricate the skin during a massage session. ⁽²⁸⁾
