10 Science-Backed Benefits of Sesame Oil for Health and Wellness

Sesame oil has been treasured for thousands of years across various cultures for its remarkable health properties and culinary versatility. Extracted from sesame seeds (Sesamum indicum), this golden oil has earned its reputation as one of nature’s most beneficial oils, often celebrated as the “Queen of Oilseeds” due to its impressive nutritional profile.

Rich in healthy fats, antioxidants, and bioactive compounds, sesame oil offers a wide array of health benefits that extend from internal wellness to external beauty applications. Whether you’re looking to support heart health, manage inflammation, or enhance your skincare routine, sesame oil provides science-backed solutions that have stood the test of time.

In this comprehensive guide, we’ll explore ten evidence-based benefits of sesame oil and show you how to incorporate this powerful ingredient into your daily life.

1. Powerful Antioxidant Properties

Sesame oil stands out among cooking oils for its exceptional antioxidant content. The oil contains unique compounds called sesamol, sesaminol, and sesamolin, which work together to combat oxidative stress in your body.

Antioxidants are crucial molecules that neutralize harmful free radicals—unstable compounds that can damage cells and contribute to chronic diseases and premature aging. The antioxidants in sesame oil help protect your cells from this damage, supporting overall health and longevity.

Research has demonstrated that regular consumption of sesame oil can increase antioxidant activity in the body, providing enhanced protection against cellular damage. These protective effects may help reduce the risk of various health conditions associated with oxidative stress, including cardiovascular disease and certain types of cancer.

The oil’s antioxidant properties remain stable even when heated, making it an excellent choice for cooking compared to other oils that may lose their beneficial compounds during the heating process.

2. Reduces Inflammation Throughout the Body

Chronic inflammation is at the root of many modern health problems, from arthritis to heart disease. Sesame oil has been used in traditional medicine systems for centuries to address inflammatory conditions, and modern science is now validating these traditional uses.

The anti-inflammatory compounds in sesame oil work by reducing the production of inflammatory markers in the body. Studies have shown that sesame oil can decrease levels of nitric oxide and other pro-inflammatory substances that contribute to tissue damage and pain.

Traditional practitioners have long used sesame oil topically to treat joint inflammation, dental pain, and various skin irritations. The oil’s ability to penetrate deeply into tissues makes it particularly effective when applied externally for inflammatory conditions.

By incorporating sesame oil into your diet or skincare routine, you may experience reduced inflammation, which can lead to improved comfort, better mobility, and decreased risk of inflammation-related diseases.

3. Supports Cardiovascular Health

Heart disease remains one of the leading health concerns worldwide, making heart-healthy dietary choices more important than ever. Sesame oil offers significant cardiovascular benefits thanks to its ideal fatty acid composition.

The oil contains approximately 82% unsaturated fatty acids, including both monounsaturated and polyunsaturated fats. These healthy fats are known to support heart health by helping to maintain healthy cholesterol levels and reducing the risk of arterial plaque buildup.

Sesame oil is particularly rich in omega-6 fatty acids, which play an essential role in cardiovascular function when consumed in appropriate amounts. Research suggests that replacing saturated fats with unsaturated fats like those found in sesame oil can lead to improvements in blood lipid profiles.

Studies have found that regular consumption of sesame oil may help reduce LDL (bad) cholesterol and triglyceride levels while supporting healthy blood vessel function. The combination of healthy fats and antioxidants makes sesame oil a heart-smart choice for cooking and food preparation.

4. Helps Regulate Blood Sugar Levels

Maintaining stable blood sugar levels is crucial for everyone, but especially for individuals with diabetes or prediabetes. Sesame oil may offer valuable support for blood sugar management through multiple mechanisms.

Research indicates that sesame oil consumption can help improve insulin sensitivity and support more stable blood glucose levels. The bioactive compounds in sesame oil appear to influence how the body processes and utilizes sugar, potentially reducing blood sugar spikes after meals.

Studies have shown that incorporating sesame oil into the diet may lead to improvements in both short-term blood sugar control and long-term markers of glycemic management, such as hemoglobin A1c (HbA1c) levels.

For individuals managing diabetes, adding sesame oil to a balanced diet—under the guidance of a healthcare provider—may complement other blood sugar management strategies. The oil’s beneficial effects on blood sugar appear to work alongside its anti-inflammatory and antioxidant properties to support overall metabolic health.

5. May Alleviate Arthritis Symptoms

Arthritis affects millions of people worldwide, causing joint pain, stiffness, and reduced mobility. Sesame oil shows promise as a natural approach to managing arthritis symptoms and improving joint health.

The oil’s anti-inflammatory properties make it particularly beneficial for conditions like osteoarthritis, where inflammation plays a key role in joint deterioration and pain. Research suggests that both consuming sesame oil and applying it topically to affected joints may provide relief.

Studies have demonstrated that sesame oil can help reduce markers of oxidative stress in joint tissues while decreasing inflammatory compounds that contribute to arthritis symptoms. Some individuals report experiencing less joint pain and improved flexibility when using sesame oil regularly.

Sesame oil massage has been used in traditional healing practices for joint health, and many people find that gentle massage with warm sesame oil provides soothing relief for aching joints. While more human research is needed, current evidence suggests that sesame oil may be a valuable addition to arthritis management approaches.

6. Promotes Wound Healing and Skin Repair

Sesame oil has a long history of topical use for skin health, including the treatment of wounds, burns, and various skin conditions. Modern research is beginning to uncover the mechanisms behind these traditional applications.

When applied to the skin, sesame oil may accelerate wound healing by promoting the production of collagen, a structural protein essential for skin repair and regeneration. The oil’s antimicrobial properties also help protect wounds from infection during the healing process.

Some practitioners use ozonated sesame oil—sesame oil infused with ozone gas—for enhanced wound healing properties. This specialized preparation has shown promising results in promoting faster healing and better tissue regeneration in research studies.

The combination of antioxidants, anti-inflammatory compounds, and fatty acids in sesame oil creates an optimal environment for skin healing. Whether dealing with minor cuts, burns, or skin irritation, sesame oil may offer gentle, natural support for the skin’s healing processes.

7. Provides Natural UV Protection

While sesame oil should not replace your regular sunscreen, it does offer some natural protection against ultraviolet (UV) radiation damage. This property makes it a beneficial addition to your skincare routine, particularly for everyday UV exposure.

Research suggests that sesame oil can resist approximately 30% of UV rays, thanks to its antioxidant content and natural chemical structure. This is higher than many other plant oils, including coconut, olive, and peanut oils, which typically block around 20% of UV rays.

The oil’s UV-protective effects likely stem from its antioxidants, which help neutralize free radicals generated by sun exposure. These free radicals contribute to premature skin aging, sunburn, and increased skin cancer risk.

While sesame oil can provide supplemental protection and may help reduce oxidative damage from incidental sun exposure, it’s important to continue using broad-spectrum sunscreen for extended outdoor activities or intense sun exposure. Consider sesame oil as a complementary skincare ingredient rather than a sunscreen replacement.

8. Enhances Hair Health and Strength

Sesame oil has been used in hair care traditions around the world for centuries, valued for its ability to nourish, strengthen, and beautify hair. Modern research is confirming many of these traditional uses.

The oil’s rich composition of vitamins, minerals, and fatty acids makes it an excellent treatment for dry, damaged, or brittle hair. Sesame oil penetrates the hair shaft, providing deep conditioning and helping to prevent protein loss from hair strands.

Regular use of sesame oil on hair may help increase shine, improve manageability, and reduce breakage. The oil forms a protective coating around hair strands, shielding them from environmental damage and heat styling.

Research has shown that compounds in sesame oil, particularly sesamin, may help strengthen hair and improve its overall quality. Some studies have found that supplements containing sesamin and vitamin E led to measurable improvements in hair strength and luster.

For best results, warm sesame oil can be massaged into the scalp and hair, left on for 30 minutes to several hours, then washed out with a gentle shampoo. This deep conditioning treatment can be done weekly or as needed for optimal hair health.

9. Supports Better Sleep Quality

Quality sleep is essential for overall health and wellbeing, yet many people struggle with sleep issues. Interestingly, sesame oil may offer support for better sleep through both internal and external use.

In traditional wellness practices, sesame oil has been used to promote relaxation and improve sleep quality. Some research suggests that topical application of sesame oil, particularly on the forehead or scalp, may help induce relaxation and support more restful sleep.

The oil contains compounds that may influence neurotransmitter activity and promote a sense of calm. Additionally, the practice of self-massage with warm sesame oil before bedtime can be deeply relaxing, helping to reduce stress and prepare the body for sleep.

Studies have found that regular sesame oil treatments may improve both sleep quality and overall quality of life. The oil’s calming properties, combined with the soothing ritual of application, create a holistic approach to better sleep.

Consider incorporating a gentle sesame oil scalp massage into your evening routine as a natural way to unwind and promote more restful sleep.

10. Offers Natural Pain Relief

Sesame oil’s anti-inflammatory and analgesic properties make it a valuable natural option for managing various types of pain. Topical application of sesame oil has been shown to provide relief from muscle soreness, joint pain, and other discomforts.

The oil’s ability to penetrate deeply into tissues allows its beneficial compounds to reach affected areas effectively. When used for massage, sesame oil may help reduce pain perception while promoting relaxation and improving circulation to painful areas.

Research has demonstrated that massage with sesame oil can help reduce pain in the extremities and improve comfort levels. The warming quality of sesame oil makes it particularly soothing for muscular tension and stiffness.

Traditional healing systems have long employed sesame oil for pain management, using it for everything from headaches to arthritis pain. While it’s not a replacement for medical treatment for serious conditions, sesame oil massage may provide complementary relief for everyday aches and pains.

For pain relief, warm sesame oil slightly and massage it gently into affected areas. The combination of the oil’s therapeutic properties and the massage technique itself can provide significant comfort.

How to Choose and Use Sesame Oil

To maximize the benefits of sesame oil, it’s important to select the right type and use it appropriately. Several varieties of sesame oil are available, each suited to different purposes.

Light or unrefined sesame oil has a pale color and mild, nutty flavor. This type is ideal for cooking at low to medium temperatures and works well in salad dressings and light sautéing.

Refined sesame oil undergoes more processing, resulting in a neutral flavor and higher smoke point. This variety is best for high-heat cooking methods like deep-frying or stir-frying.

Toasted sesame oil is made from roasted sesame seeds and has a dark brown color with an intense, nutty aroma. This oil is typically used as a finishing oil or flavoring agent rather than for cooking, as heat can diminish its delicate flavor.

For therapeutic or cosmetic use, choose cold-pressed, unrefined sesame oil to ensure maximum retention of beneficial compounds.

Easy Ways to Incorporate Sesame Oil into Your Life

Adding sesame oil to your daily routine is simple and can enhance both your culinary experiences and wellness practices. Here are practical ways to use sesame oil:

In Cooking:

• Drizzle toasted sesame oil over stir-fried vegetables or noodles for added flavor
• Use light sesame oil for sautéing vegetables, tofu, or lean proteins
• Add sesame oil to marinades for meat, fish, or vegetable dishes
• Whisk sesame oil into vinaigrettes and salad dressings
• Incorporate into sauces, dips, and condiments for depth of flavor

For Health and Beauty:

• Perform oil pulling with sesame oil for oral health (swish 1 tablespoon for 10-15 minutes before spitting out)
• Use as a natural moisturizer for dry skin
• Massage warm sesame oil into scalp and hair as a conditioning treatment
• Apply to minor skin irritations or dry patches
• Use for self-massage (abhyanga) as part of a relaxation routine

Potential Considerations and Safety

While sesame oil is generally safe for most people, there are a few considerations to keep in mind:

Allergies: Sesame allergy is becoming increasingly common. If you have a known sesame allergy, avoid all sesame products, including sesame oil.

Caloric content: Like all oils, sesame oil is calorie-dense, containing approximately 120 calories per tablespoon. Use it in moderation as part of a balanced diet.

Omega-6 intake: While omega-6 fatty acids are essential, consuming them in excess relative to omega-3 fatty acids may contribute to inflammation. Balance sesame oil use with omega-3 rich foods like fatty fish, walnuts, and flaxseeds.

Quality matters: Choose high-quality, preferably organic sesame oil from reputable sources to ensure purity and maximum nutrient content.

If you’re considering using sesame oil for specific health conditions or have concerns about how it might interact with existing health issues, consult with a healthcare provider for personalized guidance.

Storage and Shelf Life

To maintain sesame oil’s beneficial properties and prevent rancidity, proper storage is essential. Store sesame oil in a cool, dark place away from direct sunlight and heat sources. A pantry or cupboard away from the stove is ideal.

Unrefined sesame oil should be used within six months of opening, while refined sesame oil typically lasts up to a year when stored properly. Always check for signs of rancidity, including an off smell or bitter taste, before using.

Some people prefer to refrigerate sesame oil to extend its shelf life, though this may cause the oil to become cloudy or semi-solid. Simply bring it to room temperature before use, and it will return to its normal consistency.

The Bottom Line
