Theoretically, taking ashwagandha with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, taking ashwagandha with antihypertensive drugs might increase the risk of hypotension.
Details
Animal research suggests that ashwagandha might lower systolic and diastolic blood pressure (19279). Theoretically, ashwagandha might have additive effects when used with antihypertensive drugs and increase the risk of hypotension.
|
Theoretically, taking ashwagandha might increase the sedative effects of benzodiazepines.
Details
There is preliminary evidence that ashwagandha might have an additive effect with diazepam (Valium) and clonazepam (Klonopin) (3710). This may also occur with other benzodiazepines.
|
Theoretically, taking ashwagandha might increase the sedative effects of CNS depressants.
Details
Ashwagandha seems to have sedative effects. Theoretically, this may potentiate the effects of barbiturates, other sedatives, and anxiolytics (3710).
|
Theoretically, taking ashwagandha might decrease the effects of immunosuppressants.
Details
|
Ashwagandha might increase the effects and adverse effects of thyroid hormone.
Details
Concomitant use of ashwagandha with thyroid hormones may cause additive therapeutic and adverse effects. Preliminary clinical research and animal studies suggest that ashwagandha boosts thyroid hormone synthesis and secretion (19281,19282,97292). In one clinical study, ashwagandha increased triiodothyronine (T3) and thyroxine (T4) levels by 41.5% and 19.6%, respectively, and reduced serum TSH levels by 17.4% from baseline in adults with subclinical hypothyroidism (97292).
|
Theoretically, concomitant use of cowhage and anesthesia might increase the risk of arrhythmias.
Details
Cowhage contains levodopa (7020,7205,46334,46336,94723,94724). Use of levodopa with cyclopropane or halogenated hydrocarbon anesthesia has led to arrhythmias. Other anesthetics have not been implicated (15). Use other anesthetics in patients taking cowhage or tell patients to stop taking cowhage at least 2 weeks before surgery.
|
Theoretically, concomitant use of cowhage and antidiabetes drugs might increase the risk of hypoglycemia.
Details
Animal research shows that cowhage might have hypoglycemic effects (7221).
|
Theoretically, use of cowhage might decrease the clinical effects of antipsychotic drugs.
Details
|
Theoretically, concomitant use of cowhage and guanethidine might increase the risk of hypotension.
Details
|
Concomitant use can increase the risk of levodopa-related adverse effects.
Details
|
Theoretically, concomitant use of cowhage and methyldopa might increase the risk of hypotension.
Details
|
Theoretically, concomitant use of cowhage and non-selective MAOIs might increase the risk of hypertensive crisis.
Details
|
Theoretically, use of TCAs might reduce the levels and clinical effects of cowhage.
Details
|
Taking tribulus with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Clinical research shows that Tribulus can lower blood glucose levels in adults with type 2 diabetes who are taking antidiabetes medications (97327).
|
Theoretically, taking tribulus with antihypertensive drugs might increase the risk of hypotension.
Details
|
Theoretically, tribulus might increase the levels and clinical effects of lithium.
Details
Tribulus is thought to have diuretic properties (12681). Due to these potential diuretic effects, tribulus might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Below is general information about the adverse effects of the known ingredients contained in the product HisSynergy. 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
...Orally, ashwagandha seems to be well-tolerated.
Topically, no adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Diarrhea, gastrointestinal upset, nausea, and vomiting. However, these adverse effects do not commonly occur with typical doses.
Serious Adverse Effects (Rare):
Orally: Some case reports raise concerns about acute liver failure, hepatic encephalopathy, and the need for liver transplantation with ashwagandha treatment.
Dermatologic ...Orally, dermatitis has been reported in three of 42 patients in a clinical trial (19276).
Endocrine ...A case report describes a 73-year-old female who had taken an ashwagandha root extract (unspecified dose) for 2 years to treat hypothyroidism which had been previously managed with levothyroxine. The patient was diagnosed with hyperthyroidism after presenting with supraventricular tachycardia, chest pain, tremor, dizziness, fatigue, irritability, hair thinning, and low thyroid stimulating hormone (TSH) levels. Hyperthyroidism resolved after discontinuing ashwagandha (108745).
Gastrointestinal ...Orally, large doses may cause gastrointestinal upset, diarrhea, and vomiting secondary to irritation of the mucous and serous membranes (3710). When taken orally, nausea and abdominal pain (19276,110490) and gastritis and flatulence (90651) have been reported.
Genitourinary ...In one case report, a 28-year-old male with a decrease in libido who was taking ashwagandha 5 grams daily over 10 days subsequently experienced burning, itching, and skin and mucous membrane discoloration of the penis, as well as an oval, dusky, eroded plaque (3 cm) with erythema on the glans penis and prepuce (32537).
Hepatic ...Orally, ashwagandha in doses of 154-1350 mg daily has played a role in several case reports of liver injury. In most of these cases, other causes of liver injury were excluded, and liver failure did not occur. Symptoms included jaundice, pruritus, malaise, fatigue, lethargy, weight loss, nausea, diarrhea, abdominal pain, stool discoloration, and dark urine. Symptom onset was typically 5-180 days from first intake, although in some cases onset occurred after more than 12 months of use (102686,107372,110490,110491,111533,111535,112111). Laboratory findings include elevated aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase, and serum bilirubin (112111). In most cases, liver enzymes normalized within 1-5 months after discontinuation of ashwagandha (102686,107372,110491,111535,112111). However, treatment with corticosteroids, lactulose, ornithine, ursodeoxycholic acid, and plasmapheresis, among other interventions, was required in one case (111533). Rarely, use of oral ashwagandha has been reported to cause hepatic encephalopathy and liver failure requiring liver transplantation (110490).
Neurologic/CNS ...Orally, ashwagandha has been reported to cause drowsiness (110492). Headache, neck pain, and blurry vision have been reported in a 47-year-old female taking ashwagandha, cannabis, and venlafaxine. Imaging over the course of multiple years and hospital admissions indicated numerous instances of intracranial hemorrhage and multifocal stenosis of intracranial arteries, likely secondary to reversible cerebral vasoconstriction syndrome (RCVS) (112113). It is unclear whether the RCVS and subsequent intracranial hemorrhages were precipitated by ashwagandha, cannabis, or venlafaxine.
General
...Orally, adverse effects to cowhage seem to be rare; however, a thorough safety evaluation has not been conducted.
Topically, cowhage bean pod or seed may be unsafe.
Most Common Adverse Effects:
Orally: Diarrhea, flatulence, mucosal irritation.
Topically: Erythema, pruritus, rash.
Cardiovascular ...Orally, cowhage has been reported to cause palpitations (7021,7203)
Dermatologic
...Orally, ingestion of hairs from the bean pod or seed can result in significant mucosal irritation and should be avoided.
Topically, hairs on cowhage bean pod or seed can cause severe pruritus (6898). Symptoms include severe itching, burning, inflammation, and erythematous macular rashes (18,6898). Symptoms resolve spontaneously within several hours, but may also be relieved with antihistamines (6898). The hairs can be removed from the skin by washing, but the hairs can also be retained, and transferred to other people, in fabrics and carpets. Clothing and other materials that come in contact with cowhage hairs should also be thoroughly washed (6898).
Gastrointestinal ...Orally, cowhage has been reported to cause flatulence, diarrhea, and dry mouth (7021,7203). Orally, a specific powdered cowhage seed extract (Zandopa, formerly HP-200; Zandu Pharmaceuticals) has been reported to cause nausea, abdominal distention, and vomiting in clinical research when taken in amounts of 22.5-67.5 grams divided into 2-5 doses per day (7020).
Musculoskeletal ...Orally, dyskinesia has been reported in clinical research in about 3% of patients taking a specific powdered cowhage seed extract (Zandopa, formerly HP-200; Zandu Pharmaceuticals) 22. 5-67.5 grams divided into 2-5 doses daily (7020).
Neurologic/CNS ...Orally, cowhage has been reported to cause headaches (7021,7203). Orally, insomnia has been reported in clinical research in about 3% of patients taking a specific powdered cowhage seed extract (Zandopa, formerly HP-200; Zandu Pharmaceuticals) 22.5 grams to 67.5 grams divided into 2-5 doses daily (7020).
Psychiatric ...In a case report, cowhage caused an outbreak of acute toxic psychosis. Symptoms of psychosis included confusion, giddiness, agitation, hallucinations, and paranoid delusions. The cowhage-induced psychosis was successfully treated with intravenous chlorpromazine (7021).
Other ...Orally, cowhage has been reported to cause sweating and changes in urine color, (7021,7203). Theoretically, due to the levodopa constituent, cowhage is likely to cause the same adverse effects that have been attributed to purified, prescription levodopa. Some of these side effects include elevated liver enzymes, respiratory disturbances, urinary retention, muscle cramps, and priapism (15). However, these effects have not yet been reported for cowhage.
General
...Orally, tribulus seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Cases of liver and kidney injury, seizures, and chronic painful erection with impaired sexual function have been reported. Pneumothorax and bronchial polyp after consuming the spine-covered tribulus fruit have been reported.
Gastrointestinal ...Orally, tribulus can cause abdominal pain, cramping, nausea, vomiting, diarrhea, and constipation (92022,92027). However, in one study, the rates of these gastrointestinal complaints were similar for patients taking tribulus and those receiving placebo (92022).
Genitourinary ...In one case report, a patient taking two tribulus tablets (unknown dose) daily for 15 days presented to the local emergency department with a painful erection lasting 72 hours. The priapism was resolved with medical management; however, post-episode sexual function was impaired (92023).
Hepatic ...In one case report, a patient drinking tribulus water 2 liters daily for two days presented with lower limb weakness, seizures, hepatitis, and acute kidney injury. The patient's condition improved after hemodialysis and discontinuation of tribulus water (92069).
Neurologic/CNS ...Orally, tribulus has been reported to cause general excitation and insomnia. These symptoms were reversed upon discontinuation of the drug or decreasing the dose (78867). In one case report, a patient drinking tribulus water 2 liters daily for two days presented with lower limb weakness, seizures, hepatitis, and acute kidney injury. The patient's condition improved after hemodialysis and discontinuation of tribulus water (92069).
Pulmonary/Respiratory ...In one case report, a patient developed a bilateral pneumothorax after consuming the spine-covered fruit of tribulus (818). In another case report, a patient developed a polyp in the lobar bronchus of the right interior lobe due to the presence of a tribulus fruit spine (78852).
Renal ...In one case report, a patient drinking tribulus water 2 liters daily for two days presented with lower limb weakness, seizures, hepatitis, and acute kidney injury. The patient's condition improved after hemodialysis and discontinuation of the tribulus water (92069). In another case report, a healthy male taking one tribulus tablet (unknown dose) daily for a few months for bodybuilding purposes developed hyperbilirubinemia followed by acute kidney failure 2-3 weeks later. The patient was managed with intravenous fluids and a low-salt, low-protein diet (92025).
Other ...In one case report, gynecomastia was observed in a male weightlifter taking an herbal combination product containing tribulus. However, it is not clear if this adverse effect can be attributed to tribulus alone (78859).
