LIKELY SAFE ...when used orally in amounts commonly found in foods. Dill has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts (12). There is insufficient reliable information available about the safety of dill when used topically.
PREGNANCY: POSSIBLY UNSAFE
when used in medicinal amounts.
Dill seed is used to stimulate menstrual flow (19). Theoretically, dill seed might adversely affect pregnancy.
LACTATION:
Insufficient reliable information available; avoid amounts greater than those found in foods.
LIKELY SAFE ...when used orally and appropriately. Evening primrose oil has been used safely in doses up to 6 grams daily for up to 1 year (7566,7567,8926,12036,20512,49286,49360,109426). There is insufficient reliable information available about the safety of evening primrose oil when used topically. There is also insufficient reliable information available about the safety of evening primrose seed, flower, or leaf when used orally or topically.
CHILDREN: POSSIBLY SAFE
when evening primrose oil is used orally and appropriately, short-term.
In children up to 5 years of age, doses of evening primrose oil up to 3 grams daily have been used safely for 5 months (20512,49273), and 0.5 grams/kg daily has been used safely for 8 weeks (7570). In children up to 12 years of age, doses of 4-6 grams daily have been used safely for 3-5 months (7565,7566,20512,49286). ...when used topically and appropriately, short-term. In children 2-10 years of age, evening primrose oil has been applied to affected areas of the skin twice daily for up to 3 months (96718). There is insufficient reliable information available about the safety of evening primrose seed, flower, or leaf when used orally or topically.
PREGNANCY: POSSIBLY SAFE
when evening primrose oil is used orally and appropriately.
In small studies of evening primrose oil for pre-eclampsia, 4 grams has been used orally daily for up to 10 weeks during pregnancy with apparent safety (1409,20525). Evening primrose oil has also been used safely during the last week of pregnancy to improve cervical ripening (20524,96717), although in one retrospective case series improvement was lacking and there was a trend toward prolonged labor, increased rates of arrest of descent, and increased oxytocin requirements (1411). Evening primrose oil has also been linked to a case report of petechiae and ecchymoses in a newborn infant whose mother took a total of 6.5 grams during the week before giving birth (16303); use with caution, especially in high doses.
LACTATION: POSSIBLY SAFE
when evening primrose oil is used orally.
Supplementation with evening primrose oil during lactation results in the secretion of high levels of the constituent gamma linolenic acid into breast milk (1982); however, this fatty acid is normally present in significant amounts in breast milk (11884).
LIKELY SAFE. ..when used orally in food amounts. The flowers, seeds, leaves, and rhizomes of lotus are all edible (95261). There is insufficient reliable information available about the safety of medicinal lotus.
PREGNANCY AND LACTATION:
Insufficient reliable information available on the medicinal use of lotus; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Weight Loss Pills. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, dill extract might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia. Animal research shows that dill extract can reduce blood sugar levels (47799,47817). Monitor blood glucose levels closely. Dose adjustments might be necessary.
 Details
Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), and others.
|
Dill is thought to have diuretic properties (11). Theoretically, due to these potential diuretic effects, dill might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.
|
Theoretically, evening primrose oil may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
Evening primrose oil contains gamma linolenic acid (GLA). There is preliminary clinical evidence that GLA can reduce platelet aggregation and prolong bleeding time (1979).
|
Theoretically, evening primrose may increase the levels and clinical effects of CYP2C9 substrates.
Details
In vitro research shows that linoleic acid, a constituent of evening primrose oil, inhibits CYP2C9 (21017).
|
Theoretically, concomitant use of lithium with evening primrose oil might decrease lithium levels and effects.
Details
In a case report, a patient on a stable dose of lithium for 10 years experienced a reduction in lithium levels after taking evening primrose oil 500 mg daily. Baseline levels were 0.69 mmol/L, which decreased to 0.37 mmol/L after 2 months and 0.23 mmol/L after 3 months of use. Lithium levels increased within 6 weeks of discontinuing evening primrose oil, to 0.73 mmol/L; no clinical effects were noted (96715).
|
Theoretically, evening primrose oil might increase the levels and effects of lopinavir.
Details
In a case report, an HIV patient who took evening primrose oil (Efamol) along with lopinavir/ritonavir experienced an increase in serum levels of lopinavir to 15.2 mg/L. Six weeks after discontinuing evening primrose oil, levels of lopinavir returned to the normal range of 5-10 mg/L. When re-challenged with evening primrose oil for a week, the patient's lopinavir levels increased from 6.69 to 8.11 mg/L. It is suspected that evening primrose oil increases levels of lopinavir by inhibiting cytochrome P450 3A4 (CYP3A4), which metabolizes lopinavir (93578). However, this effect has not been reported in other research.
|
Theoretically, taking evening primrose oil with phenothiazines might increase the risk of convulsions.
Details
Evening primrose oil contains gamma-linolenic acid (GLA). There is some concern that taking supplements containing GLA might cause seizures, or lower the seizure threshold, when taken with phenothiazines (88187). In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with GLA, although none experienced an actual seizure (21013). In another report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose oil 4 grams daily was added. One of these patients had a prior history of seizures (21010). It is unclear whether evening primrose oil had any additive epileptogenic effects with the phenothiazines; there is no evidence that taking evening primrose oil alone causes seizures (88187).
|
Theoretically, concurrent use of lotus with other antiplatelet drugs might reduce platelet aggregation and increase the risk of bleeding.
Details
|
Theoretically, lotus might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.
Details
Animal research shows that the ethanolic extract of lotus reduces blood glucose levels and potentiates the effects of injected insulin (60053). Monitor blood glucose levels closely. Dose adjustments might be necessary.
|
Theoretically, taking lotus concomitantly with pentobarbital might increase sedation.
Details
Animal research shows that lotus extract increases pentobarbitone-induced sleeping time (60051). It is not known if this occurs in humans or if this effect occurs with other barbiturates or sedatives.

General
...Orally, dill is well tolerated when used in amounts commonly found in foods (4912).
Dill seems to be well tolerated when used as medicine (12). However, a thorough evaluation of safety outcomes has not been conducted. Some people are allergic to dill (47751,47753).
Topically, photodermatosis is possible after contact with juice from freshly harvested plants (19). Dill can also cause contact dermatitis (19,47767,47773).
Dermatologic ...Topically, photodermatosis is possible after contact with juice from freshly harvested plants (19).
Immunologic
...Orally, there are case reports of individuals allergic to dill (47751,47753).
In one case, symptoms, including swelling around the eyes, itching, rash, and chapped lips, occurred after a delay of 12 hours (47751). In another case, immediate symptoms of anaphylaxis, as well as vomiting and diarrhea, occurred following intake and inhalation of foods cooked with dill (47753).
Topically, dill has resulted in contact dermatitis (47767,47773).
General
...Orally and topically, evening primrose oil is generally well tolerated.
There is limited reliable information available regarding the safety or adverse effects of other parts of the plant.
Most Common Adverse Effects:
Orally: Abdominal pain and distention, diarrhea, dyspepsia, flatulence, nausea, and vomiting.
Dermatologic ...Orally, use of evening primrose oil has been associated with reports of skin rash and acne (9156,9794,49338). There is a case report of extensive but transient petechiae and purpuric ecchymoses in a newborn infant whose mother had consumed raspberry leaf tea and a total of 6.5 grams of evening primrose oil orally and vaginally during the week prior to delivery. The infant had a normal platelet count and no signs of hemorrhage, and was discharged healthy at 3 days of age (16303).
Gastrointestinal ...Gastrointestinal complaints, including abdominal pain, distension and fullness, nausea and vomiting, diarrhea, dyspepsia, and flatulence are the most common adverse effects of evening primrose (8926,9794,20533,49188,49286,49339,49365,65864,88184,102556). Often these effects resolve with continued use. Altered taste has also been reported (49339).
Hematologic ...There is preliminary clinical evidence that evening primrose oil can decrease platelet aggregation and prolong bleeding time. In a small study of patients with hyperlipidemia, taking evening primrose oil 3 grams daily for 4 months was associated with a 40% increase in bleeding time, and decreases in ADP- and epinephrine-induced platelet aggregation of 50% and 60% respectively (1979). There is also a case report of diffuse ecchymoses and petechiae in a neonate whose mother had consumed 6.5 grams of evening primrose oil over the week prior to delivery (16303).
Neurologic/CNS
...Cases of dizziness (9794) and headache (88184) have been reported with evening primrose oil when used orally.
There is a report of seizures in a patient taking evening primrose oil and receiving anesthesia; however, the patient was also taking other drugs and it is therefore unclear if evening primrose was the cause (613). There is also concern that evening primrose oil might cause seizures, or lower the seizure threshold, in patients with schizophrenia who are treated with phenothiazines. This is based on limited data from two studies published in the 1980s. In one report, three patients with schizophrenia who had received phenothiazines developed EEG changes suggestive of temporal lobe epilepsy after starting treatment with evening primrose, although none experienced an actual seizure (21013). In the other report, two patients with schizophrenia who were stabilized on phenothiazines developed seizures when evening primrose oil 4 grams daily was added. One of these patients had a prior history of seizures (21010). There is no evidence that evening primrose taken alone, without medications known to lower the seizure threshold, can cause seizures (88187).
Other ...Weight gain has been reported in individuals receiving evening primrose oil (49338).
General ...Orally, adverse effects to lotus seem to be rare when taken in medicinal amounts; however, a thorough safety evaluation has not been conducted.
Immunologic ...Orally and topically, lotus root can cause allergic reactions such as urticaria and contact dermatitis. In a case report, a 6-year-old female developed urticaria after ingesting lotus root. She had also developed contact dermatitis on body areas that had been in contact with the lotus root (99738).
