Bija Toasted Sesame Oil by Flora

POSSIBLY EFFECTIVE

• Hypertension. Oral sesame oil seems to reduce blood pressure by a small amount. Details: Meta-analyses of clinical research involving patients with or without hypertension show that taking sesame, or the sesame constituent sesamin, can reduce both systolic blood pressure (SBP) and diastolic blood pressure (DBP) (96179,108355,108357). One meta-analysis of eight clinical studies shows that sesame or sesamin can reduce SBP by 8 mmHg and DBP by 6 mmHg when compared with control. In a subgroup analysis of patients with hypertension, reductions in SBP and DBP were 11 mmHg and 9 mmHg, respectively. In a subgroup analysis by formulation, sesame oil was shown to reduce SBP and DBP by 13 mmHg and 10 mmHg, respectively, while whole sesame seed, ground seed, or sesame supplement lowered SBP by only 3 mmHg and did not lower DBP (96179). Another meta-analysis of clinical studies involving patients with hypertension, metabolic syndrome, or kidney failure shows that taking sesame oil reduces SBP and DBP by 3 mmHg and 2 mmHg, respectively, although benefits were limited to studies of less than 8 weeks (108355). Some research on sesame oil involved replacing other cooking oils with a specific brand of sesame oil (Idhayam Gingelly oil, V.V.V. & Sons) 35 grams daily for about 6-9 weeks. Patients included in these studies were also using atenolol, nifedipine, and/or hydrochlorothiazide as antihypertensives (27652,27654,27655). Other preliminary clinical research shows that using a 20:80 blend of sesame oil and rice bran oil (Vivo, Adani Wilmar) as cooking oil for 8 weeks improves blood pressure and lipid profile in patients with hypertension. In patients using nifedipine, using the oil blend seems to reduce systolic and diastolic blood pressure by an additional 2 to 2.2-fold over nifedipine alone (96180).

POSSIBLY INEFFECTIVE

• Cough. Oral sesame oil does not seem to be beneficial for cough in children. Details: Clinical research in children with an acute cough due to common cold shows that taking sesame oil 5 mL by mouth at bedtime for 3 consecutive days does not reduce cough strength or cough frequency when compared with placebo (27647).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aging skin. Although there is interest in using topical sesame oil for aging skin, there is insufficient reliable information about the clinical effects of sesame for this purpose.
• Alzheimer disease. Although there is interest in using oral sesame for Alzheimer disease, there is insufficient reliable information about the clinical effects of sesame for this condition.
• Anemia of chronic disease. Although there is interest in using oral sesame for anemia of chronic disease, there is insufficient reliable information about the clinical effects of sesame for this condition.
• Anxiety. Although there is interest in using topical sesame oil for anxiety, there is insufficient reliable information about the clinical effects of sesame for this purpose.
• Bowel obstruction. It is unclear if oral sesame oil is beneficial for bowel obstruction. Details: Preliminary clinical research in adults with adhesive small bowel obstruction shows that giving sesame oil 150 mL through a nasogastric tube along with standard treatment reduces the need for surgical intervention when compared with standard treatment alone. Also, the resolution time of the obstruction was 6 hours faster and the duration of hospitalization was 4 days shorter for patients treated with sesame oil plus standard treatment when compared with standard treatment alone (27645). Standard treatment consisted of stopping oral intake of food, performing nasogastric tube decompression, administering intravenous fluids with electrolytes, and providing parenteral antibiotics if leukocytosis was present.
• Burns. It is unclear if topical sesame oil is beneficial for burns. Details: Preliminary clinical research in adults and children with partial thickness thermal burns covering less than 40% of body surface area shows that topical application with a moist exposed burn ointment (MEBO) containing sesame oil, beta-sitosterol, berberine, and other unspecified plant ingredients every 4 hours reduces the median time to 75% healing by 3 days (17 days vs. 20 days) and improves analgesic effects during the first 5 days of treatment when compared with a control group receiving cleansing with chlorhexidine 0.05%. The MEBO was left on the burn for 5 days, followed by removal and reapplication at 4 hourly intervals on day 5, to be left on until day 14 (13526).
• Cardiovascular disease (CVD). Although there is interest in using oral sesame for CVD, there is insufficient reliable information about the clinical effects of sesame for this condition.
• Cataracts. Although there is interest in using oral sesame for cataracts, there is insufficient reliable information about the clinical effects of sesame for this condition.
• Chemotherapy-induced phlebitis. It is unclear if massage with topical sesame oil is beneficial for chemotherapy-induced phlebitis. Details: Preliminary clinical research in patients with colorectal cancer and chemotherapy-induced phlebitis shows that applying 10 drops of sesame oil within a 10 cm radius of the affected veins as part of a 5-minute, twice-daily massage reduces pain after 7 days when compared with massage alone (103227).
• Child growth. It is unclear if massage with topical sesame oil is beneficial for child growth. Details: Preliminary clinical research in full-term healthy infants shows that administering a daily massage with sesame oil 20 mL for 4 weeks improves infant length by 1 cm, midarm circumference by 0.9 cm, and midleg circumference by 0.7 cm when compared with a control group that did not receive a massage (29722). It is unclear if these effects are due to sesame oil, massage, or the combination.
• Cognitive impairment. It is unclear if oral sesame is beneficial for cognitive impairment. Details: Clinical research in older adults with memory impairment shows that taking sesame oil cake extract (Keukdong H-Pharm Co., Ltd.) 500 mg three times daily for 12 weeks modestly improves some, but not all, measures of cognitive function when compared with placebo (108351). In addition, preliminary clinical research in patients with mild cognitive impairment shows that taking two capsules of a combination product containing the sesame constituent sesamin 5 mg and astaxanthin 3 mg daily for 12 weeks increases psychomotor and processing speed when compared with placebo. However, there was no effect on memory, attention, or overall severity of cognitive symptoms (99863). It is not clear if these effects are due to sesamin, astaxanthin, or the combination.
• Dental plaque. It is unclear if rinsing the mouth with sesame oil or pulling the oil through the teeth is beneficial for dental plaque. Details: Preliminary clinical research in children 12-14 years of age shows that rinsing with 10 mL of ozonated or non-ozonated sesame oil for 10 minutes daily for 15 days reduces plaque when compared with baseline. The ozonated sesame oil was superior to non-ozonated sesame oil, showing a similar improvement in plaque when compared with chlorhexidine mouthwash (103226). A small clinical study in healthy adults shows that pulling sesame oil 10 mL through the teeth for 15-20 minutes twice daily for 4 days has similar effects on full-mouth prevention of plaque regrowth, tooth staining, gingival index, and bleeding when compared with pulling coconut oil through the teeth (106038).
• Diabetes. It is unclear if oral sesame oil is beneficial for diabetes. Details: Meta-analyses suggest that taking sesame for 6-12 weeks modestly reduces levels of fasting blood glucose and glycated hemoglobin (HbA1c), but not insulin levels or insulin resistance, when compared with placebo, baseline, or other control. Sesame oil and seed flour, tahini, and sesamin were used in the included research (108350,108352,108355). Although most studies included in these meta-analyses were conducted in patients with type 2 diabetes, one study (103231) was conducted in patients with metabolic syndrome. One small clinical trial included in these meta-analyses shows that replacing other cooking oils with a specific brand of sesame oil (Idhayam Gingelly oil, V.V.V. & Sons) 35 grams daily for 45 days reduces blood glucose levels and HbA1c when compared with baseline in patients with diabetes who are also using glibenclamide (27654). Sesame oil has also been investigated in combination with rice bran oil. One preliminary clinical trial in patients with type 2 diabetes not using antidiabetes medications shows that using a specific 20:80 blend of sesame oil and rice bran oil (Vivo, Adani Wilmar) as the only cooking oil for 8 weeks reduces levels of fasting blood glucose by 14% and reduces HbA1c when compared with baseline. In patients taking glibenclamide 5 mg daily, using this oil blend reduces fasting blood glucose and HbA1c when compared with glibenclamide alone (96177). The use of sesame oil has also been investigated for improving cardiometabolic markers in patients with type 2 diabetes. Clinical research in adults taking antidiabetes medications shows that replacing regular dietary oils with sesame oil or a blend of sesame and canola oils for 9 weeks does not improve most cardiometabolic markers when compared with canola oil or sunflower oil as a control (108353).
• Gastric cancer. Although there is interest in using oral sesame for gastric cancer prevention, there is insufficient reliable information about the clinical effects of sesame for this purpose.
• Gingivitis. It is unclear if pulling sesame oil through the teeth is beneficial for gingivitis. Details: Preliminary clinical research in adolescent males with plaque-induced gingivitis shows that oil pulling with sesame oil for one minute daily each morning prior to brushing for 10 days reduces dental plaque and gingivitis when compared with baseline (27648). The validity of this finding is limited by the lack of a comparator group.
• Hemorrhoids. Topical sesame oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small study in adults with symptomatic mild to moderate (first- and second-degree) internal hemorrhoids shows that application of a cream containing sesame oil and aqueous extracts of guggul and Allium ampeloprasum as a thin layer to the anus twice daily for 3 weeks improves anal irritation and itching, bleeding, pain, defecation discomfort, and swelling sense when compared with baseline. In contrast, patients using a placebo cream experienced an improvement only in anal itching (105751). The poor study methodology and lack of statistical comparison to the placebo group limit the validity of these findings.
• HIV/AIDS-related wasting. Oral sesame has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in adults with HIV shows that consuming 300 grams of a chickpea and sesame-based food supplement daily for 3 months, along with routine sulfamethoxazole-trimethoprim, improves weight gain, body mass index, and mid-upper arm circumference in 73% of patients, and results in improved physical performance in 78% of patients, when compared to baseline (27657). The validity of these findings is limited by the lack of a comparator group.
• Hyperlipidemia. It is unclear if oral sesame is beneficial for hyperlipidemia. Details: A meta-analysis of a limited number of clinical studies that included mainly patients without hyperlipidemia shows that consuming sesame 25-50 grams daily or using sesame oil 3.5-35 grams daily for up to 10 weeks does not reduce levels of total or low-density lipoprotein (LDL) cholesterol when compared with baseline (96181). However, a more recent meta-analysis with similar studies shows that consuming sesame reduces levels of total cholesterol by 16 mg/dL, although there is no effect on levels of LDL cholesterol or high-density lipoprotein (HDL) cholesterol (108357). Both analyses show that taking sesame reduces triglyceride levels by about 21 mg/dL (96181,108357). Significant heterogeneity of the included studies and patient populations limits the validity of these results.
• Insect repellent. Although there is interest in using topical sesame oil as an insect repellent, there is insufficient reliable information about the clinical effects of sesame for this purpose.
• Male infertility. It is unclear if oral sesame is beneficial for male infertility. Details: Preliminary clinical research in males with infertility shows that taking sesame 0.5 mg/kg daily for 3 months modestly improves sperm count and motility, but not sperm morphology, when compared with baseline (108356). The validity of these findings is limited by the lack of a comparator group.
• Menopausal symptoms. Although there is interest in using oral sesame for menopausal symptoms, there is insufficient reliable information about the clinical effects of sesame for this purpose.
• Metabolic syndrome. It is unclear if oral sesame oil is beneficial for improving metabolic parameters in adults with metabolic syndrome. Details: Preliminary clinical research in patients with metabolic syndrome shows that taking sesame oil 30 mL with or without vitamin E 400 mg daily for 8 weeks improves levels of fasting blood glucose, lipids, and blood pressure when compared with sunflower oil. In those taking sesame oil alone, total cholesterol and triglycerides were reduced by about 13 mg/dL, while low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol were not affected. In those also taking sesame oil with vitamin E, total cholesterol and triglycerides were reduced by 17 mg/dL and 21 mg/dL, respectively, while HDL cholesterol was increased by 4 mg/dL. Additionally, systolic and diastolic blood pressure were reduced by 10 mmHg and 8 mmHg, respectively, in those taking sesame oil alone, versus 15 mmHg and 9 mmHg, respectively, in those taking sesame oil with vitamin E (103231).
• Miscarriage. It is unclear if oral sesame is beneficial for the management of an incomplete miscarriage. Details: Preliminary clinical research in patients with incomplete abortion related to miscarriage shows that taking sesame seed twice daily for 5 days results in complete resolution of retained products of conception in 84% of individuals, based on a sonographic assessment, compared with 26% of those receiving expectant management as control. There was also a 2-day reduction in the duration of vaginal bleeding when compared with control. Each dose of ground sesame seed powder 30 grams was boiled in 200 mL water for 4 minutes and then filtered before drinking (108346).
• Nonalcoholic fatty liver disease (NAFLD). It is unclear if oral sesame oil is beneficial for NAFLD. Details: Clinical research in females with NAFLD shows that taking sesame oil 30 grams daily for 12 weeks reduces the severity of fatty liver in 89% of patients taking sesame oil, compared with 58% of those taking sunflower oil. There were also modest reductions in levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT), but not alkaline phosphatase (ALP), when compared with sunflower oil. All patients were also consuming a 500-kcal hypocaloric diet (108354).
• Obesity. It is unclear if oral sesame is beneficial for weight loss. Details: Meta-analyses of clinical research show that taking sesame or sesame oil in doses of at least 35 grams daily reduces body weight by up to 2 kg and body mass index by up to 1 kg/m² when compared with no oil or a control oil. Clinical studies included in these meta-analysis enrolled patients with type 2 diabetes, hypertension, hypercholesterolemia, and others, and were not limited to overweight or obese individuals (108355,108357). A small clinical study in overweight individuals shows that replacing regular dietary oil with sesame oil for 9 weeks does not improve levels of most cardiometabolic risk factors, although there were modest beneficial effects on insulin (108349).
• Osteoarthritis. It is unclear if topical sesame oil is beneficial for knee osteoarthritis. Details: Preliminary clinical research in patients with osteoarthritis of the knee shows that applying sesame oil 1.5 mL to the affected knee three times daily for 4 weeks reduces pain and improves physical function when compared to baseline. These improvements were similar to those seen in patients applying diclofenac topical gel (103228).
• Osteoporosis. Although there is interest in using oral sesame for osteoporosis, there is insufficient reliable information about the clinical effects of sesame for this condition.
• Pain (acute). It is unclear if massage with topical sesame oil is beneficial for acute pain caused by blunt trauma. Details: One small clinical study shows that using a specific sesame oil (Saman sesame oil, Saman sesame oil Co.) topically as part of a light massage for 5 minutes twice daily for 9 days moderately reduces acute pain caused by blunt trauma to an extremity by day 6 when compared with a light massage with placebo oil. However, the sesame oil massage does not reduce the use of nonsteroidal anti-inflammatory drugs when compared with placebo oil (96178). A similar clinical study in the same population shows that using sesame oil extracted from tahini topically as part of a light massage for 5 minutes 3 times a day for 2 days improves pain severity, pain sensitivity, and heaviness of the painful site by about 20% when compared with baseline (106034). The lack of statistical comparison to the placebo group limits the validity of these findings.
• Peptic ulcers. Although there is interest in using oral sesame for peptic ulcers, there is insufficient reliable information about the clinical effects of sesame for this purpose.
• Rheumatoid arthritis (RA). It is unclear if oral sesame is beneficial for RA. Details: Preliminary clinical research in females with RA shows that taking the sesame constituent sesamin (Sesamin, Scivation, Inc.) 200 mg daily for 6 weeks improves physical function and reduces pain, the number of tender and swollen joints, and markers of inflammation such as C-reactive protein when compared with placebo (103230).
• Stroke. Although there is interest in using oral sesame for stroke, there is insufficient reliable information about the clinical effects of sesame for this purpose. More evidence is needed to rate sesame for these uses.

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Taking sesame oil with antidiabetes drugs might increase the risk of hypoglycemia.  Details Clinical studies show that sesame oil can decrease plasma glucose and glycated hemoglobin (HbA1c) levels. Some clinical research in patients taking glibenclamide shows that using sesame oil or a blend of sesame oil and rice bran oil in place of other oil for cooking reduces plasma glucose more than glibenclamide alone (27654,28139,96177,108350,108352,108355). Monitor blood glucose levels closely. Dose adjustments might be necessary.

ANTIHYPERTENSIVE DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Probable •  Level of Evidence = D Taking sesame oil with antihypertensive drugs might increase the risk of hypotension.  Details Clinical research shows that replacing other cooking oil with sesame oil can lower systolic blood pressure (SBP) and diastolic blood pressure (DBP) in patients with or without hypertension. There is also some evidence that sesame oil has additive effects in patients also taking atenolol, nifedipine, and/or hydrochlorothiazide (27652,27654,27655,96179,108355,108357). In patients using nifedipine, using a blend of sesame oil and rice bran oil for cooking reduces both SBP and DBP more than nifedipine alone (96180).

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, sesame might increase the levels and clinical effects of CYP2C9 substrates.  Details In vitro, sesame inhibits CYP2C9 (11028). However, this interaction has not been reported in humans.

P-GLYCOPROTEIN SUBSTRATES Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = D Theoretically, sesame might alter the transport of P-glycoprotein substrates.  Details In vitro research suggests that sesamin, a constituent of sesame, can inhibit the multi-drug transporter protein, P-glycoprotein (28319,28320). However, this interaction has not been reported in humans.

TAMOXIFEN (Nolvadex) Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, sesame might interfere with tamoxifen.  Details In animal research, sesame seed reduces the tumor-inhibitory effect of tamoxifen by reducing apoptosis and increasing proliferation (28110,28111). This interaction has not been reported in humans.

General ...Orally, topically, or intranasally, sesame seems to be well tolerated.
Most Common Adverse Effects:
All routes of administration: Allergic reactions.

Dermatologic ...In a small clinical study, one patient using a cream containing sesame oil as well as aqueous extracts of guggul and Allium ampeloprasum complained of rash at the application site (105751). It is unclear if this reaction was due to sesame, other ingredients, or other factors.

Gastrointestinal ...There was a single case of diarrhea associated with oral sesame in a clinical trial (108356).

Immunologic ...Multiple cases of allergic response to sesame seed occurring after occupational, topical, intramuscular, or oral exposure have been reported (28157,28158,28159,28160,28161,28162,28163,28166,28167,28183)(28184,28185,28186,28188,108348). One study found that up to 0.5% of the United States population reports having a sesame allergy, and 0.23% of the population meets criteria for an IgE-mediated allergic reaction to sesame (100501). Allergic symptoms may be dermatologic, such as angioedema (28160,28167,108348), cheilitis (28207), dermatitis (28157,28166,28182,28185,28186), edema (28159), erythema (28167), pruritis (28167,108348), purpura (28188), flushing (108348), and urticaria (28159,28160,28162,108348); musculoskeletal (28188); respiratory, such as asthma (28159,28162), rhinitis (28162), wheezing (28167), and general breathing difficulties (108348); gastrointestinal, such as vomiting (28159,108348); and others such as conjunctivitis (28159), anaphylactic shock (28157,28159,28160,28167,28177,28178,28179,28180,28204,108348), and hemodynamic modifications (28169). In Canada, sesame accounted for 4% of pediatric food-induced anaphylaxis reactions presenting to emergency departments over a 10-year period. The majority of cases were mild to moderate in severity and occurred within 2 hours of exposure; however, about 3% occurred 2-8 hours after exposure. Epinephrine was the most common treatment, followed by antihistamines, inhaled beta-agonists, and corticosteroids (108348).
Approximately one-third of patients with IgE-mediated sesame allergy have reported previous use of epinephrine due to this allergy (100501). There is evidence that IgE-mediated sesame allergy is influenced by both genetic and environmental factors; there was a high correlation of the allergy between family members, especially siblings (28175).
Allergens believed to be responsible for sesame seed hypersensitivity include beta-globulin (28213); sesamol, sesamolin, and sesamin (28182,28207); storage proteins including ses i 1 and ses i 2 (2S albumins) (28132,28187,28211,28212,28216,28217), ses i 3 (a 7S vicilin-type globulin) (28187,28214), ses i 4 (28158), ses i 5 (28158), ses i 6 (an 11S globulin) (28132,28215), and ses i 7 (28215). Typically allergens in sesame seeds that cause reactions after oral intake have molecular weights ranging from 8-62 kDa (28208,28210).

Pulmonary/Respiratory ...In clinical trials involving a sesame oil nasal spray, minor adverse effects included adverse smell, oil dripping from the nose, and nasal blockage (27659).
