Below is general information about the safety of the known ingredients contained in the product Dragon Time Massage Oil. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Clary sage has Generally Recognized As Safe status (GRAS) for use in foods in the US (4912). There is insufficient reliable information available about the safety of clary sage when used as medicine.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in food amounts. Coconut oil can be safely consumed as a component of the diet (12361,17935,94452,106494). However, coconut oil should not be considered a healthy alternative to other saturated fats (94453,94643). Coconut oil contains more saturated fat than animal based fats, including lard and butter (94643). Therefore, like all saturated fats, coconut oil should be used in moderation (94453,94643). ...when used topically and appropriately. Commercial products containing coconut oil in concentrations up to 100% have been used with apparent safety. However, most research has used commercial products with concentrations up to 70% (12356,17936,17941).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts, short-term. Taking coconut oil up to 10 mL orally two or three times daily for up to 12 weeks has been used with apparent safety in clinical research (17938,17942,90615,106493).

Below is general information about the adverse effects of the known ingredients contained in the product Dragon Time Massage Oil. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General ...No adverse effects reported. However, a thorough evaluation of safety outcomes has not been conducted.
General
...Orally and topically, coconut oil is generally well tolerated.
Most Common Adverse Effects:
Orally: Increased cholesterol levels.
Serious Adverse Effects (Rare):
All routes of administration: Allergic reactions, including anaphylaxis, in sensitive individuals.
Cardiovascular ...Due to its high saturated fat content, there has been some speculation that consuming coconut oil might increase cholesterol levels and the risk of cardiovascular disease. Several population and clinical studies have found that consuming coconut oil increases total cholesterol, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol in some patients (12361,14407,17935,17940,94451,94452,99103,101877,101879,106489,106494). In patients with normal to high cholesterol levels, consuming a daily diet providing 30% to 36% of calories from fat, of which 46% to 66% is from coconut oil, for 4-12 weeks increases total cholesterol by about 12-15 mg/dL, low-density lipoprotein (LDL) cholesterol by about 9-12 mg/dL, and HDL cholesterol by 3-6 mg/dL when compared to a diet containing vegetable oils, especially those rich in polyunsaturated fatty acids (17935,94451,94452,101877,106489). In some cases, these cholesterol effects are similar to those seen in patients consuming a similar diet containing butter or beef fat (12361,17935,94451,99103,101879). Despite the potential effects of coconut oil on cholesterol levels, population research has not found an association with coconut oil consumption and risk of adverse cardiovascular events such as myocardial infarction or angina (14407,96205). Advise patients not to rely on coconut oil as a "healthy" alternative to other saturated fats.
Dermatologic ...In one case report, a 6-year-old child developed urticaria and hives from applying coconut oil to the skin. The child had been exposed to coconut oil consistently since 2 weeks of age, indicating sensitization over the course of regular exposure (95806). In clinical research, one patient reported localized pruritus immediately after applying a combination of coconut oil, anise oil, and ylang ylang (13483). It is unclear if this event was due to coconut oil, other ingredients, or the combination. Also, it is possible that this was an idiosyncratic event.
Gastrointestinal ...Orally, diarrhea and gastroenteritis have been reported rarely (101877).
Hepatic ...Orally, taking virgin coconut oil in the diet for 28 days modestly increased levels of liver enzymes in patients with coronavirus disease 2019 (COVID-19). However, it is unclear if this was due to the coconut oil or to the illness (107664).
Immunologic
...Several cases of allergic reactions have been reported for patients who consumed coconut fruit.
In some of the cases, the patients were previously diagnosed with sensitivity to other tree nuts, including peanuts, so cross-sensitivity is suspected. In a separate case report, a 17-year-old male was found to be sensitized to both coconut and buckwheat, indicating a possible cross-sensitivity between the two allergens (95808). In other cases, the patients did not show sensitivity to any other allergens, so the patients were considered to have a single allergy to coconut fruit (12359,12360).
Because coconut oil is derived from coconut fruit, ingestion of coconut oil may theoretically cause allergic reactions in patients with confirmed allergy to coconut fruit. In one case report, a 6-year-old child who had previously experienced urticaria and hives from applying coconut oil to the skin experienced throat swelling and anaphylaxis after eating food containing coconut, indicating a sensitivity to both the fruit and the oil via both topical application and ingestion (95806). However, allergic reactions to coconut appear to occur significantly less often than allergies to other food items such as wheat, milk, soy, or peanut (14408).
General
...Orally and topically, fennel seems to be well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal discomfort, photosensitivity, and allergic reactions in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Seizures.
Dermatologic ...Advise patients to avoid excessive sunlight or ultraviolet light exposure while using fennel (19). Allergic reactions affecting the skin such as atopic dermatitis and photosensitivity may occur in patients who consume fennel (6178,49507).
Gastrointestinal ...Orally, fennel may cause gastrointestinal complaints, including nausea and vomiting (19146,104196).
Hematologic ...Methemoglobinemia has been reported in four infants following intoxication related to ingestion of a homemade fennel puree that may have been made from improperly stored fennel (49444).
Immunologic ...A case report describes an 11-year-old male who developed an allergy to fennel-containing toothpaste. Immediately after using the toothpaste, the patient experienced sneezing, coughing, itchy mouth, rhinorrhea, nasal congestion, wheezing, difficulty breathing, and palpitations, which resolved within 10 minutes of spitting out the toothpaste and rinsing the mouth. In challenge tests, the patient reacted to chewing fresh fennel root, but not ground fennel seeds (103822).
Neurologic/CNS ...Orally, fennel oil has been associated with tonic clonic and generalized seizures (12868). New-onset cluster headaches are reported in a 24-year-old female while using a toothpaste containing fennel and camphor for 3 months. The headaches resolved upon stopping the toothpaste (112368). It is unclear if this adverse effect can be attributed to fennel, camphor, or the combination.
Pulmonary/Respiratory ...Orally, fennel and fennel seed have been reported to cause bronchial asthma (49478).
General
...Orally, the whole fruit, as well as the seed, fruit, and leaf extracts, seem to be well tolerated.
Topically, grape seed extracts seem to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, dry mouth, dyspepsia, headache, joint pain, and nausea.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis to grape skin has been reported.
Dermatologic ...Orally, mild hair thinning has been reported in a patient taking a specific grape leaf extract AS195 KG) (2538). Urticaria (hives) has also been reported with this same extract (53206). Cases of contact dermatitis have been reported in grape workers, including those working in California vineyards (53270,53272,53275).
Gastrointestinal ...Orally, abdominal pain and nausea have been reported with use of grape seed extract, but these effects typically occur at rates similar to placebo (9182,13162). In a case report of a 57-year-old man, intermittent nausea, vomiting, and diarrhea occurred over a 10-day period and improved once grape seed extract was stopped (96764). Gastrointestinal adverse effects have also been reported with use of a different grape seed extract (Entelon, Hanlim Pharm). However, the specific types of gastrointestinal effects were not described (100954). A specific grape leaf extract AS195 (Antistax, Boehringer Ingelheim Pharma GmbH & Co. KG) has reportedly caused flatulence, mild constipation, gastrointestinal discomfort, diarrhea, dyspepsia, dry mouth, and retching (2538,52985,53206). Diarrhea, gastrointestinal distress, indigestion, and aversion to taste have been reported with use of Concord grape juice (52972,53166,53175,53181,53199). Loose stools have been reported in a clinical trial of grape pomace (99270). Bowel obstruction caused by intact grapes and grape seeds has been described in case reports (53241,53284,53278).

Sore throat, cough, allergic rhinitis, and nasopharyngitis have been reported with use of grape seed extract, but these effects occur at rates similar to placebo (9182,91541). One case report describes a 16-year-old female who developed increased levels of immunoglobulin E (IgE) following skin-prick exposure to grape vine pollen, as well as positive test responses following bronchial and conjunctival provocation (53301). Reduced forced vital capacity has been described in California grape workers (53080,53081). Occupational eosinophilic lung was diagnosed in a grape grower with a history of asthma. Respiratory exposure to sulfites in grape was implicated as the cause of the adverse reaction (53285).
Other
...Orally, grape products can cause adverse effects due to contamination with pesticides or mycotoxins.
Some evidence has shown that pesticides used in vineyards may remain on grape surfaces post-harvesting. For example, the fungicide folpet sprayed on grapevines has been shown to remain on the grape surface. Although there was minimal penetration of the epicuticular wax, it showed high resistance to washing (52935). Carbaryl has been identified in over 58% of juice samples collected in Canada. This pesticide reportedly occurred more frequently in grape than in other juices. However, estimates of short-term intake were below proposed acute reference doses (53003).
Ochratoxin A is a mycotoxin that is suspected to be nephrotoxic, teratogenic, hepatotoxic and carcinogenic and has been identified in grape juice, frozen grape pulps, and red and white wine sold in Rio de Janeiro, Brazil. However, the highest levels identified in grape products were lower than the established virtually safe dose of 5 ng/kg of body weight daily (53010,53004). Ochratoxin A has also been identified in red, but not white, grape juice marketed in Switzerland, Canada, and the U.S. (53292,53020).
General ...Topically, jasmine may cause allergic contact dermatitis, delayed-type hypersensitivity, and type 1 hypersensitivity (56955,57027,57032,98684).
Immunologic ...Topically, jasmine essential oil and jasmine flower can cause allergic contact dermatitis (56955,57027,57032). Among patients who are sensitive to fragrance materials, jasmine may cause delayed-type hypersensitivity. The reported prevalence of this type of reaction ranges from 0.4% to 1.6% (89684). One case of type 1 hypersensitivity to jasmine has also been reported. The patient experienced chest tightness, wheezing, itchy skin, and macular erythematous eruption within minutes of exposure to jasmine. The eruption subsided within 20 minutes of moving away from the plant. An immunoblotting assay revealed IgE reactivity (98684).
General
...Orally, lavender is well tolerated in food amounts and seems to be well tolerated in larger amounts.
Topically, lavender oil seems to be well tolerated.
Most Common Adverse Effects:
Orally: Breath odor, constipation, diarrhea, dyspepsia, eructation, headache, and nausea.
Topically: Allergic contact dermatitis (with lavender oil).
Serious Adverse Effects (Rare):
Topically: Cases of gynecomastia have been reported in prepubertal males using lavender oil.
Cardiovascular ...Orally, a specific lavender oil ingredient (Silexan) has been associated with palpitations (103061).
Endocrine ...Topical products containing lavender oil alone, including a product referred to as agua de violetas, or in combination with tea tree oil have been linked to at least six cases of gynecomastia when used in prepubertal males. In each case, gynecomastia resolved when the lavender oil products were discontinued. It is thought that the estrogenic and antiandrogenic activity of lavender oil and tea tree oil resulted in gynecomastia in these cases (15254,95643).
Gastrointestinal ...Orally, lavender oil, including a specific lavender oil ingredient KG), may cause gastrointestinal disturbance, including dyspepsia, diarrhea, breath odor, eructation, and nausea (58077,58080,58098,93004,103061). Tincture of lavender has been linked to cases of constipation and increased appetite; however, it is unknown if this occurred at a greater rate than with placebo (9792).
Immunologic ...Topically, use of lavender oil, such as in personal care products, might cause allergic contact dermatitis in some patients (6,101728). There have been numerous case reports of allergic contact dermatitis and eczema linked to lavender oil exposure from shampoos, lotions, fragrances, or direct application of oil to pillows (10031,58043,58109,58120,101728,112253). In one case series, only 4 out of 15 cases of allergic contact dermatitis due to lavender had positive patch tests for lavender. Oxidation products of lavender essential oils such as linalool, linalyl acetate, limonene, cineol, geraniol, eugenol, and isoeugenol may be more allergenic than un-oxidized lavender essential oil, which may result in a false negative patch test (112253).
Neurologic/CNS ...Orally, lavender flower powder, tincture of lavender containing 50% alcohol, and a specific lavender oil ingredient (Silexan) have been linked to headache (9792,103061,109860). Headache has also been reported rarely following lavender oil aromatherapy (109860).
Pulmonary/Respiratory ...In one case report, a 34-year-old Japanese female presented with complaints of dyspnea, cough, and fever 2 weeks after initiating lavender essential oil therapy via humidifier. The patient had an oxygen saturation of 88% and was diagnosed with acute eosinophilic pneumonia. Symptoms improved after a course of corticosteroids and discontinuation of aromatherapy (109979).
Renal ...In one case report, a 24-year-old male presented with shortness of breath, weakness, nausea, and decreased urine output following the intake of Spanish lavender tea twice daily for 5 days. After presenting to the hospital, the patient was diagnosed with acute kidney failure secondary to acute interstitial nephritis likely due to lavender consumption (112259).
General
