In 2004, Canada began regulating natural medicines as a category of products separate from foods or drugs. These products are officially recognized as "Natural Health Products." These products include vitamins, minerals, herbal preparations, homeopathic products, probiotics, fatty acids, amino acids, and other naturally derived supplements.
In order to be marketed in Canada, natural health products must be licensed. In order to be licensed in Canada, manufacturers must submit applications to Health Canada including information about uses, formulation, dosing, safety, and efficacy.
Products can be licensed based on several criteria. Some products are licensed based on historical or traditional uses. For example, if an herbal product has a history of traditional use, then that product may be acceptable for licensure. In this case, no reliable scientific evidence is required for approval.
For products with non-traditional uses, some level of scientific evidence may be required to support claimed uses. However, a high level of evidence is not necessarily required. Acceptable sources of evidence include at least one well-designed, randomized, controlled trial; well-designed, non-randomized trials; cohort and case control studies; or expert opinion reports.
Finished products licensed by Health Canada must be manufactured according to Good Manufacturing Practices (GMPs) as outlined by Health Canada.

POSSIBLY SAFE ...when used orally and appropriately. Devil's claw extract has been used with apparent safety in doses of up to 2400 mg daily for up 12 weeks (6472,8608,14332,14418,47112,47114,47116,47117,47155). There is insufficient reliable information available about the safety of devil's claw when used orally long-term or when used topically.
PREGNANCY: POSSIBLY UNSAFE

Most Common Adverse Effects:
Orally: Allergic skin reactions, diarrhea, dyspepsia.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal bleeding.
Cardiovascular ...In one case report, a healthy patient with normal blood pressure presented with hypertension after taking devil's claw 250 mg twice daily for 2 weeks. It gradually resolved after discontinuation of devil's claw (92017). Some animal research shows that devil's claw might have negative chronotropic, as well as positive and negative inotropic, effects (8609). However, these effects have not been documented in humans.
Dermatologic ...Rarely, allergic skin reactions have been reported in patients taking devil's claw (8608,14418).
Endocrine ...In one case report, a 65-year-old female developed psychomotor agitation, nausea, and distress from euvolemic hyponatremia secondary to inappropriate secretion of antidiuretic hormone (SIADH) within 1 month of starting daily treatment with devil's claw. Within 5 days of discontinuing the product and receiving sodium replacement, the symptoms resolved. Two months later, the patient re-initiated devil's claw and again developed euvolemic hyponatremia (96747).
Gastrointestinal ...Gastrointestinal side effects, including mild gastrointestinal upset, diarrhea, anorexia, acid reflux, or loss of taste, have been reported in some individuals receiving devil's claw, especially at high doses (6472,8608,8613,14332,14418,47112,47116,47144,47169).
