• Atopic dermatitis (eczema). It is unclear if oral hemp seed oil is beneficial in patients with eczema. Details: A small preliminary clinical trial in patients with eczema shows that taking hemp seed oil 30 mL daily for 8 weeks improves skin dryness, itchiness, and use of dermal medication when compared with baseline, but not when compared with an olive oil control (101125).
• Constipation. Oral hemp seed has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Clinical research in patients with functional constipation shows that taking a proprietary Chinese herbal medicine (Hemp Seed Pill) containing hemp seed, rhubarb root, peony root, apricot kernel, bitter orange fruit, and magnolia bark twice daily for 8 weeks results in a response rate to 43%, compared with 8% in those taking placebo. The response rate was defined as an increase of at least 1 complete spontaneous bowel movement per week. This combination product also improved the responder rate in the 2 weeks after treatment, as well as the overall use of rescue therapy, when compared with placebo (101127). Data from this study pooled with data from another larger study in adults with functional constipation shows that this same product increases the likelihood of complete response, defined as at least 3 complete spontaneous bowel movements per week or an increase over baseline of at least 1 weekly, by 1.43 times when compared with placebo. Complete spontaneous bowel movements per week also increased by 1 when compared with placebo (107319). It is unclear if these effects are due to hemp seed, other ingredients, or the combination.
• Dysmenorrhea. Although there is interest in using oral hemp for dysmenorrhea, there is insufficient reliable information about the clinical effects of oral hemp for this condition.
• Familial hypercholesterolemia. It is unclear if oral hemp seed oil is beneficial in children with this condition. Details: A small preliminary clinical trial shows that taking hemp seed oil (AlfaLife, Freia Farmaceutici Srl) 3 grams daily for 8 weeks does not improve levels of total or low-density lipoprotein (LDL) cholesterol when compared with no treatment in hyperlipidemic children aged 6-16 years who are also following a low-fat diet with high fruit and vegetable intake (101144).
• Joint pain. Although there is interest in using oral hemp for joint pain, there is insufficient reliable information about the clinical effects of oral hemp for this condition.
• Multiple sclerosis (MS). Oral hemp seed has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with relapsing-remitting MS shows that taking a combination of hemp seed oil 5.4-6.3 grams and evening primrose oil three times daily for 6 months seems to improve disability scores and relapse rate when compared to baseline. However, the control group in this study ingested olive oil and also experienced notable improvements in disability and relapse rates (88183). This study is limited due to high dropout rate and because there was no statistical comparison between treatment and control groups.
• Obesity. It is unclear if an oral cannabidiol-rich hemp oil extract helps to improve weight loss. Details: A small clinical study in healthy overweight adults shows that taking a specific hemp oil extract (PlusCBD Extra Strength Hemp Extract, CV Sciences) as 60 mg, providing 15 mg cannabidiol, daily for 6 weeks, does not reduce weight or body mass index when compared with placebo (103805). The validity of this study is limited due to its exploratory nature and lack of control for voluntary dietary changes.
• Osteoarthritis. It is unclear if oral hemp seed is beneficial in patients with osteoarthritis. Details: A clinical study in 18 older adults with osteoarthritis undergoing in-hospital rehabilitation following knee or hip arthroplasty shows that consuming pasta enriched with hemp seed flour for 6 weeks improves pain scores by about 3 points, compared with only 1 point in those consuming a regular pasta control (107320).
• Psychological well-being. Although there is interest in using oral hemp for psychological well-being, there is insufficient reliable information about the clinical effects of oral hemp for this condition. More evidence is needed to rate hemp for these uses.

• Insect repellent. Although there has been interest in using topical oregano oil as an insect repellent, there is insufficient reliable information about the clinical effects of oregano for this purpose.
• Intestinal parasite infection. It is unclear if oral oregano is beneficial in patients with intestinal parasite infections. Details: In one small, uncontrolled study, taking a specific emulsified oregano leaf oil product (ADP, Biotics Research Corporation) 200 mg orally three times daily with meals for 6 weeks resulted in eradication of Blastocystis hominis, Entamoeba hartmanni, and Endolimax nana from the stool in 10 of 13 patients (6878). The clinical significance of this is unclear since the Centers for Disease Control (CDC) considers Entamoeba hartmanni and Endolimax nana to be non-pathogenic, while blastocystosis caused by Blastocystis hominis is usually self-limiting and does not require treatment.
• Pain (acute). Although there has been interest in using topical oregano oil for the relief of acute pain, including joint and muscle pain, there is insufficient reliable information about the clinical effects of oregano for this purpose.

• Urinary tract infections (UTIs). Although there has been interest in using oral oregano for UTIs, there is insufficient reliable information about the clinical effects of oregano for this purpose.
• Varicose veins. Although there has been interest in using topical oregano oil for varicose veins, there is insufficient reliable information about the clinical effects of oregano for this purpose.
• Warts. Although there has been interest in using topical oregano oil for warts, there is insufficient reliable information about the clinical effects of oregano for this purpose.
• Wound healing. It is unclear if topical oregano is beneficial for improving healing or preventing infections in people with skin wounds. Details: One small clinical trial shows that applying an ointment containing a 3% concentration of the water-soluble fraction of the oregano plant twice daily for 10-14 days after minor dermatological surgery might reduce infection rates and improve scar formation when compared with petrolatum ointment (67348). More evidence is needed to rate oregano for these uses.

ACE INHIBITORS (ACEIs) Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, consuming hemp seed protein isolate with ACE inhibitors might have additive effects and increase the risk of hypotension.  Details Hemp seed protein hydrolysate has shown ACE inhibitor-like effects in a hypertensive animal model (101136). However, hempseed oil consumption does not seem to reduce blood pressure in humans (101144). Until more is known, monitor blood pressure and potassium levels.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Minor Be watchful with this combination. Severity = Mild •  Occurrence = Possible •  Level of Evidence = D Theoretically, hemp seed might increase the risk of bleeding when used concomitantly with anticoagulant/antiplatelet drugs.  Details In animal research, hemp seed at 5% of the diet inhibits platelet aggregation in vitro (101137). However, in human research, taking hemp seed oil 2 grams daily for 12 weeks does not inhibit the aggregation of platelets in vitro (16791).

ANTIHYPERTENSIVE DRUGS Interaction Rating = Minor Be watchful with this combination. Severity = Moderate •  Occurrence = Unlikely •  Level of Evidence = D Theoretically, hemp seed protein may have additive effects with antihypertensive drugs.  Details In a hypertensive animal model, hemp seed protein hydrolysate reduced systolic blood pressure by a mechanism possibly involving the inhibition of renin and angiotensin converting enzyme (ACE) activities. However, there was no effect of hemp seed protein on blood pressure in normotensive animals (101136). Furthermore, hempseed oil consumption does not seem to reduce blood pressure in humans (101144).

ESTROGENS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, hemp might interfere with hormone therapy due to its estrogenic effects.  Details In an ovariectomized animal model, a diet containing hemp seed 1%, 2%, or 10% resulted in normalized plasma levels of 17-beta-estradiol (101132). The mechanism of action for this effect is unclear.

General ...Orally, hemp products are generally well tolerated in food amounts. In larger amounts, hemp seed oil seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Rare cases of anaphylaxis have been reported. Long QT syndrome, torsades de pointes, and syncope have also been reported rarely.

Cardiovascular ...Acquired long QT syndrome, torsades de pointes, and syncope have been reported in a 56-year-old woman following the intake of supplements containing hemp oil. The hemp supplements provided cannabidiol (CBD), and possibly cannabigerol (CBG). Although the exact dose is unknown, up to six times the recommended dose had been used for approximately 6 weeks, in combination with a supplement containing berberine. While hospitalized, intravenous magnesium and saline were used to stabilize heart rhythm. It is unknown whether this adverse effect was related to the hemp oil, berberine, or their interaction (110104).

Hepatic ...Orally, there is a case report of elevated liver enzymes and hepatitis in a two-year-old boy given hemp extract 2. 5 mL, providing 125 mg phytocannabinoid, five to eight times daily for infantile spasms and refractory seizures. The total dose of phytocannabinoids was approximately 60-100 mg/kg daily (110287).

Immunologic ...Orally, there are case reports of allergy to hemp seed, although this is uncommon (101140,101154). A 44-year-old male developed hives during a meal of hemp seed-crusted seafoods. Later, he developed facial swelling, shortness of breath, and problems speaking. Evaluation revealed allergy to a specific protein in hemp seed. He did not react to smoked cannabis (101140). In other cases, anaphylaxis, facial swelling, and worsening asthma have been reported in association with a first exposure to hemp seed, although some had smoked cannabis previously (101154).
Topically, a case of patch-test confirmed allergic contact dermatitis to hemp seed oil has been reported in a 22-year-old woman. The initial rash started at the application point on her back and spread to her arms, hands, and neck (110288).
Airborne exposure to hemp pollen is a relatively common cause of allergic respiratory symptoms in some locations (101155).

Neurologic/CNS ...Orally, cases of acute cannabinoid toxicity with neurological symptoms in children and adults have been associated with intake of hemp seed oil. There is a case report of decreased alertness, stupor, bloodshot eyes, and fixed gaze in a 2-year-old male probably related to the intake of one teaspoon hemp seed oil (CANAH) containing 0.06% delta-9-tetrahydrocannabinol (THC) twice daily for 3 weeks. After stopping the oil, irritability was reported over the next few days (101153).

General ...Orally, oregano is well tolerated when used in amounts typically found in foods. There is currently a limited amount of information available about the safety of oregano when used in larger amounts as medicine.
Most Common Adverse Effects:
Orally: Gastrointestinal upset.
Topically: Dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Systemic allergic reactions, including anaphylaxis, in sensitive individuals.

Dermatologic ...Oregano has been reported to cause allergic contact dermatitis (46902). Topically, oregano oil in concentrations of greater than 1% has been reported to cause irritation when applied to mucous membranes (67348,88188).

Gastrointestinal ...Orally, large amounts of oregano can cause gastrointestinal upset. Concentrated, non-emulsified oil of oregano can cause localized irritation of the gastrointestinal tract (6878).

Immunologic ...Systemic allergic reactions have been reported with oregano. A 45-year-old male developed pruritus, respiratory difficulty, hypotension, swelling of the lips and tongue, and facial edema after ingesting pizza seasoned with oregano. He had 2 similar episodes after ingesting foods seasoned with thyme, another member of the Lamiaceae family. He did not react to similar foods without the seasoning, and he had positive skin tests to plants of the Lamiaceae family (3705).
