Sesame Seeds

Sesame seeds come from Sesamum indicum, one of the oldest cultivated oilseed crops in human history. They are thought to have originated in Africa and India, and the plant grows as an upright annual herb, sometimes reaching around 2 metres in height, with seed pods that hold numerous small, oil-rich seeds. Sesame seeds come in white, black and yellow varieties, with white seeds more common in Western cooking and black seeds more widely used in Asian dishes.
In Ayurveda, sesame, known as Til, is traditionally classified as having a madhura (sweet) rasa, ushna virya (heating potency), and is traditionally considered to pacify Vata dosha while increasing Pitta and Kapha if taken in excess. It is valued both as a food and, as sesame oil, for external use in massage.

Sesame seeds are known by many names across languages and regions:

• Botanical name: Sesamum indicum
• English: Sesame
• Hindi, Bengali and Sanskrit: Til
• Tamil: Ellu, Til
• Malayalam: Ellu, Achelu
• Telugu: Nuvvulu, Til
• Japanese: Goma
• Chinese: Zhi ma
• Persian: Kunjad
• Arabic: Simsim

Sesame seeds are packed with essential vitamins, minerals, healthy fats, and protein, making them valuable to a balanced diet. The nutritional value of Sesame seeds is as follows USDA FoodData Central, 2019):

Based on traditional use and early research, sesame seeds and sesame oil are associated with the following properties:

• Emollient: traditionally used to soften and soothe the skin
• Antioxidant: may help reduce oxidative stress in the body’s cells
• Anti-inflammatory: may have anti-inflammatory effects, although human evidence is limited
• Laxative: the oil content is traditionally believed to support digestion and bowel movement

Topical sesame oil has also been studied in small clinical trials for easing discomfort in specific medical settings, including vein inflammation caused by chemotherapy and pain after limb injury. This is a specific clinical use rather than a general Ayurvedic property, and should only be tried alongside a doctor’s guidance, particularly for anyone undergoing cancer treatment.

Sesame seeds provide healthy fats, vitamin E and antioxidant compounds such as sesamin that may support overall health. As part of a balanced diet, they may support healthy cholesterol and blood sugar levels, cardiovascular wellbeing and normal inflammatory balance (Jafari et al., 2025). Evidence for specific effects on liver, kidney or other health conditions remains limited, so sesame seeds should be viewed as a nutritious food rather than a treatment.

Antioxidant Support

Sesame seeds contain sesamin, a compound that may help the body manage everyday oxidative stress (Jafari et al., 2025). This nutritional benefit should not be understood as protection against any specific serious disease, and sesame seeds are not a treatment for any diagnosed condition.

Support for Healthy Cholesterol Levels

Some research suggests sesamin may help support healthy LDL and HDL cholesterol levels as part of a balanced diet (Jafari et al., 2025). Sesame seeds are not a treatment for high cholesterol or heart disease, which need a doctor’s assessment and care.

Support for Liver and Kidney Wellbeing

Early research suggests sesamin may support healthy liver enzyme levels and reduce markers of oxidative stress. Most of this evidence comes from laboratory and animal studies (Zhang et al., 2016), and sesame seeds are not a treatment for liver or kidney disease.

Support for Mild Inflammation

Sesamin has been studied for its effect on inflammatory markers in the body (Jafari et al., 2025). This potential nutritional benefit may support general comfort, but sesame seeds are not a treatment for arthritis or any other diagnosed inflammatory condition.

May Support Stable Blood Sugar Levels

Some studies suggest sesame seed oil may help support healthy fasting blood glucose levels as part of a balanced diet (Jafari et al., 2025). Sesame seeds are not a treatment for diabetes, and anyone managing diabetes should follow their doctor’s dietary advice.

Support for General Heart Wellbeing

Sesame seeds contain polyunsaturated fats and vitamin E, which may support general cardiovascular wellbeing as part of a balanced diet (Jafari et al., 2025). Sesame seeds are not a treatment for heart disease and do not replace measures known to reduce the risk of a heart attack; anyone with a heart condition should follow their doctor’s advice.

Sesame seeds are commonly used in cooking, baking and as a garnish, while their oil is widely used for cooking and traditional massage or skincare. Ground sesame seeds are also used to make tahini, a common ingredient in Middle Eastern cuisine. These uses are primarily culinary and traditional rather than medicinal.

As a Culinary Spice and Garnish

White and black sesame seeds are used in baking, cooking and garnishing, adding texture and a nutty flavour to bread, crackers and salads.

As an Extracted Oil

Sesame seeds are pressed into sesame oil, which is used in cooking and, traditionally, in massage and skincare.

As Tahini Paste

Ground sesame seeds are made into tahini, a paste widely used in Middle Eastern dishes such as hummus.

In Traditional Massage and Skincare

Sesame oil is traditionally used for facial and body massage, valued for its nourishing and potentially anti-inflammatory properties.

Sesame seeds are generally safe for most people as part of a balanced diet, but the following precautions are worth knowing:

Allergies

Sesame is a recognised food allergen. Reactions can include hives, swelling, shortness of breath and, rarely, anaphylaxis. Avoid sesame seeds and sesame oil if you have a known allergy.

Oxalate Content and Kidney Stones

Sesame seeds contain a notable amount of oxalates, which may contribute to kidney stone formation in people prone to them. Anyone with a history of kidney stones should seek medical advice before eating large amounts of sesame seeds or oil.

Digestive Comfort

Eating a large amount of sesame seeds at once can cause bloating or loose stools in some people. Start with a small amount and increase gradually.

Hormonal Effects

Sesame seeds contain phytoestrogens, plant compounds with a weak, oestrogen-like effect in the body. Anyone with a hormone-sensitive condition, or taking hormone replacement therapy, should speak with a doctor before regularly eating large amounts.

Blood Sugar Monitoring

People with diabetes can generally include sesame seeds in their diet, but should monitor their blood sugar and speak with a doctor before making a significant change to their intake.

Sesame seeds can be added to food in several ways:

In Baking

Add whole or ground sesame seeds to bread or muffin batter, or sprinkle them on top of the dough before baking for extra texture, then bake as usual.

In Cooking

Toast sesame seeds in a dry pan over medium heat for 2 to 3 minutes, stirring frequently, until golden. Add them towards the end of cooking stir-fries, salads or grain bowls, or use sesame oil in dressings and sauces for a nutty flavour.

As a Garnish

Scatter sesame seeds evenly over a finished dish, such as sushi, salad or soup, to add texture and visual appeal.

In Snacks

Combine sesame seeds with nuts, dried fruit or granola, then press the mixture into a pan and cut it into bars, or roll it into bite-sized balls.

As a food, sesame seeds do not have a strict medical dosage, but the following portion guidance can help different age groups include them as part of a balanced diet.

Children

A small amount, around 1 teaspoon, finely ground to reduce choking risk, can be introduced into meals, ideally with a paediatrician’s guidance for children with any known allergy risk.

Teenagers

Around 1 tablespoon (about 15 g) a day fits comfortably into a balanced diet.

Adults

1 to 2 tablespoons (about 15 to 30 g) a day, whole, ground or as oil, as part of a balanced diet.

Elderly

The same adult amount is generally suitable, though anyone with a history of kidney stones or a hormone-sensitive condition should check with a doctor first.

Sesame seeds are generally well tolerated, but the following effects are worth knowing about:

Weight Gain

Sesame seeds are calorie-dense. Eating them in large amounts without adjusting overall diet or activity may contribute to weight gain over time.

Reduced Calcium Absorption

Sesame seeds are high in oxalates, which can bind to calcium and reduce its absorption. This is worth knowing if you rely on sesame seeds as a major calcium source.

Effects on Thyroid Function

In sensitive individuals, eating large amounts of sesame seeds may affect thyroid function. People with a thyroid condition should speak with a doctor about an appropriate intake.

Digestive Blockage in Rare Cases

Rarely, eating a large quantity of whole sesame seeds, particularly in people with an existing digestive condition, has been linked to a blockage in the gut. This is uncommon, but anyone with persistent stomach pain after eating seeds should seek medical advice.

Sesame seeds and sesame oil may interact with certain medicines. The main ones to be aware of are:

Blood Pressure Medicines

Sesame oil may help lower blood pressure. Combined with blood pressure medicines such as ACE inhibitors, beta-blockers or calcium channel blockers, this may further lower blood pressure and could cause dizziness, fainting or fatigue. Anyone on these medicines should monitor their blood pressure and speak with a doctor before regularly using sesame oil in larger amounts.

Antidiabetic Medicines

Sesame seed oil may lower blood sugar. Combined with diabetes medicines, this could increase the risk of hypoglycaemia, or blood sugar dropping too low. Blood sugar should be monitored closely if taking both (Sankar et al., 2011).

Blood-Thinning Medicines

Sesame seeds contain vitamin E, which may affect blood clotting at high intakes. People taking blood-thinning medicines such as warfarin should keep their intake consistent and check with a doctor if increasing it significantly.

Storage of Sesame Seeds

Short-Term Storage (Pantry)

• Use an airtight glass jar or container to block air and moisture.
• Keep the container in a cool, dark place, such as a pantry or cabinet.
• Avoid spots near the stove, oven, or direct sunlight. Heat can cause the oils to become rancid more quickly.
• Raw seeds can last 3 to 6 months in the pantry. Toasted seeds can last around 3 months.

Long-Term Storage (Fridge or Freezer)

• Place seeds in airtight freezer bags or sealed glass jars.
• Store them in the refrigerator to keep raw seeds fresh for up to one year.
• Store them in the freezer to keep them fresh for up to two years.
• Let the container reach room temperature before opening it to reduce the risk of condensation forming inside.

• Sesame seeds are a nutrient-dense food that may support general wellbeing, including antioxidant intake, healthy cholesterol levels, and overall liver and kidney wellbeing, as part of a balanced diet.
• They have culinary uses as seeds, oil and tahini, and are also traditionally used in massage and skincare.
• Sesame is a recognised allergen, and sesame seeds can also cause digestive discomfort in large amounts and may affect thyroid function in sensitive individuals.
• Sesame oil may interact with blood pressure and diabetes medicines, so anyone taking these should speak with a doctor before making a significant change to their intake.
• Sesame seeds are not a treatment for any diagnosed medical condition and should be eaten in moderation, particularly by anyone with kidney stones, a thyroid condition or a hormone-sensitive condition.
