Black gram oil is a traditional Ayurvedic body oil derived from black gram (Vigna mungo), a protein-rich legume that originated in India and is commonly known as urad dal. Unlike oils pressed from high-fat seeds like sesame or sunflower, black gram seeds contain relatively little oil on their own. Most commercial black gram oil products are actually infused oils, where black gram extract is steeped in a carrier oil (typically sesame) to draw out its beneficial compounds. The result is a warming, nutrient-rich oil used primarily for massage and skin care.
How Black Gram Oil Is Made
Because black gram seeds are a legume rather than an oilseed, they don’t yield large quantities of oil through simple pressing. Instead, the traditional preparation involves cooking or soaking black gram in a base oil, usually sesame seed oil, and allowing the fat-soluble compounds to infuse over time. This method has roots in classical Ayurvedic formulation, where herbal oils are prepared by simmering plant materials in a carrier oil until the active properties transfer into the liquid.
If you see a product labeled “black gram oil,” check the ingredient list. You’ll almost always find sesame oil as the first ingredient, followed by Vigna mungo seed extract. One popular commercial example lists sesame seed oil as its base, with black gram seed extract blended alongside other Ayurvedic herbs like country mallow, velvet bean, and castor root. Pure cold-pressed black gram oil is uncommon on the market.
Its Role in Ayurvedic Medicine
In Ayurveda, black gram oil goes by the name Masha taila. One of the most well-known formulations is Mahamasha thailam, a classical medicated oil considered one of the more potent preparations for neurological and musculoskeletal conditions. “Masha” translates directly to black gram, reflecting the ingredient’s central role in the formula.
Traditional practitioners use Mahamasha thailam for a wide range of conditions: paralysis, facial palsy, locked jaw stiffness, cervical and lumbar spondylosis, rheumatoid arthritis, osteoarthritis, and general joint pain in the hands, legs, head, and neck. It’s also applied for more specific issues like frozen shoulder (both as a massage oil and administered nasally), bursitis, shoulder dislocation pain, diabetic neuropathy, varicose veins, and muscular dystrophy. For elderly patients or anyone dealing with chronic fatigue, it’s valued as a general-purpose massage oil to relieve tiredness.
The Ayurvedic rationale centers on the concept of vata, the energy governing movement and nervous system function. Bones and joints are considered primary sites of vata in the body, and joint pain is understood as a vata imbalance. Black gram is classified as one of the strongest vata-balancing foods in Ayurveda, which extends to its external application as an oil. Traditional home remedies sometimes skip the oil entirely: boiled, mashed black gram is wrapped in cotton cloth and used to massage painful joints after first applying sesame oil to the skin.
Anti-Inflammatory Properties
Modern research offers some support for these traditional uses. Extracts from Vigna mungo have been shown to reduce the activity of phospholipase A2, an enzyme that kicks off the body’s inflammatory cascade. They also lower prostaglandin production in a dose-dependent way, meaning higher concentrations produce a stronger effect. Prostaglandins are the chemical messengers responsible for pain, swelling, and inflammation at injury sites. By interrupting the chain of enzymes that converts arachidonic acid into prostaglandins, black gram extracts appear to work through a similar general pathway as common over-the-counter anti-inflammatory drugs, though the potency is not directly comparable.
These findings come from laboratory studies on black gram leaf extracts rather than the oil itself, so the degree to which these effects translate to a topical massage oil remains an open question. Still, the mechanism aligns with the traditional claim that the oil helps with joint pain and stiffness.
Skin and Body Care Uses
Black gram oil is marketed primarily as a body oil rather than a facial product. Because the base is typically sesame oil, which is naturally rich in fatty acids and vitamin E, the finished product offers solid moisturizing properties on its own. The addition of black gram extract brings extra protein-derived amino acids and antioxidant compounds like flavonoids and phenolic acids, which can help protect skin from oxidative damage.
Commercial formulations often add essential oils for fragrance and additional skin benefits. Ingredients like grapefruit peel oil, neroli flower oil, ginger root oil, and tea leaf extract are common in higher-end products. These blends are often positioned for women over 40 and 50 who want to restore skin suppleness, though there’s nothing gender-specific about the oil’s properties.
Nutritional Profile of Black Gram
Understanding what’s in the seed helps explain what ends up in the oil. Black gram belongs to the same family as mung bean (Vigna radiata), and their nutritional profiles share similarities. The fatty acid content of closely related Vigna species is dominated by linoleic acid, an omega-6 fat that typically makes up 38 to 51 percent of total fatty acids. Palmitic acid accounts for roughly 28 to 32 percent, while oleic acid is present in much smaller amounts, around 2 to 3 percent.
Linoleic acid is noteworthy for skin care because it plays a role in maintaining the skin’s barrier function. People with compromised skin barriers often have lower levels of linoleic acid in their skin lipids. The seeds also contain B vitamins (including B6 and folate), zinc, and a range of antioxidant compounds, though how much of each transfers into an infused oil depends heavily on the preparation method.
Hair and Scalp Applications
Black gram oil shows up in some hair care products, drawing on the seed’s amino acid and mineral content. The proteins in black gram support keratin production, the structural protein that makes up hair strands. Stronger keratin bonds mean less breakage and more resilient hair over time. Zinc from the extract supports hair tissue growth and repair while helping the oil glands around follicles function properly.
The antioxidant compounds, particularly flavonoids and phenolic acids, combat oxidative stress that can damage hair follicles and slow growth. When massaged into the scalp, the oil may also improve local blood circulation, delivering more oxygen and nutrients to follicles. The sesame oil base contributes its own scalp benefits by helping regulate sebum production and maintain moisture balance, which can reduce both excessive oiliness and dryness.
What to Know Before Using It
Black gram oil is generally well tolerated for topical use. Because the base is almost always sesame oil, anyone with a sesame allergy should avoid it entirely. Legume allergies are also worth considering, since black gram is closely related to other beans and lentils. If you’ve never used the product before, testing a small amount on the inside of your forearm and waiting 24 hours is a reasonable way to check for sensitivity.
It’s worth noting that black gram oil (from Vigna mungo) is an entirely different product from black seed oil (from Nigella sativa), despite the similar-sounding names. The two come from unrelated plants and have different compositions, uses, and safety profiles. If you’re shopping online, double-check the Latin name on the label to make sure you’re getting the right one.
