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.

INSUFFICIENT RELIABLE EVIDENCE to RATE
Below is general information about the safety of the known ingredients contained in the product Hawthorn Tincture (with Grain Alcohol). Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Hawthorn preparations in doses of up to 1800 mg daily seem to be safe when used for up to 16 weeks. Although hawthorn might be safe for long-term use, current studies have not evaluated safety past 16 weeks (8279,8280,8281,10144,17203,104689). There is insufficient reliable information available about the safety of hawthorn when used topically.
PREGNANCY AND LACTATION:

Theoretically, hawthorn may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
 Details
In vitro and animal research shows that hawthorn can inhibit platelet aggregation (95528,95529,95530,95531). However, its effect in humans is unclear. One observational study shows that patients taking hawthorn shortly before undergoing coronary artery bypass graft (CABG) surgery or valve replacement surgery have a 10% incidence of postoperative bleeding, compared with 1% in those who never consumed hawthorn extract (95527). However, clinical research shows that taking a specific preparation of dried hawthorn leaves and flowers (Crataesor, Soria Natural Lab) 800 mg three times daily for 15 days does not affect platelet aggregation or levels of thromboxane B2, the metabolite of thromboxane A2, in healthy humans (54664).

Theoretically, concomitant use might cause additive effects on blood pressure and heart rate.

Theoretically, concomitant use might cause additive coronary vasodilation and hypotensive effects.
Details

Theoretically, hawthorn might potentiate the effects and adverse effects of digoxin.
Details
Hawthorn appears to improve cardiac output (12595); however, hawthorn does not appear to affect digoxin pharmacokinetics (19249). Case reports suggest that at least one species of hawthorn root extract (Crataegus mexicana) may produce adverse effects similar to digoxin and can cross-react with digoxin assays, leading to falsely elevated plasma digoxin levels (113112,113113).

Theoretically, concomitant use might cause additive coronary vasodilatory effects.

Theoretically, concomitant use might result in additive vasodilation and hypotension.
Details
Hawthorn might inhibit PDE-5 and cause vasodilation (12595).

Below is general information about the adverse effects of the known ingredients contained in the product Hawthorn Tincture (with Grain Alcohol). 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, hawthorn seems to be well tolerated when used appropriately.
Topically, no adverse effects have been reported, although a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Multiorgan hypersensitivity reactions resulting in acute renal failure have been reported rarely.
Cardiovascular
...Orally, tachycardia (with facial pains) of uncertain relationship to hawthorn was reported in a multicenter clinical trial (54640).
Palpitations (19244) were reported in three patients in a large surveillance trial of 3,664 patients with cardiac failure (54692) and in 11 patients with congestive heart failure (CHF) in a literature review of 5,577 patients (19247). Circulation failure has been reported in two patients with CHF in a literature review of 5,577 patients (19247). Incidences of hospitalization, hospitalization due to CHF, worsening of CHF, angina, and atrial fibrillation have also been reported with the use of hawthorn extract WS 1442 (Crataegutt forte), although it is unclear if these events are related to hawthorn supplementation or existing CHF (19222). In clinical trials, chest pain (8281), short-term increases in blood pressure (19240), and other non-specific heart problems (17203) have also been reported following the use of various hawthorn preparations (e.g. WS 1442, Korodin).
Orally, severe bradycardia, bradypnea, and Mobitz type 1 second degree heart block have been reported in a 16-year-old female who consumed Hawthorn root extract. Blood tests indicated plasma digoxin levels in the therapeutic range, despite no history of digoxin use. Medical treatment for digoxin cardiotoxicity did not improve symptoms. Symptoms gradually normalized over 3 days after discontinuation of the product (113112). Similarly, a 40-year-old female presented with bradycardia and elevated plasma digoxin levels after taking hawthorn root extract 196 mg daily for 2 days with no history of digoxin use. Symptoms resolved within 24 hours (113113).
Dermatologic ...Orally, erythematous rash has been reported in patients with CHF in a literature review of 5,577 patients (19247). Non-specific rashes and itching (19222,19243) as well as toxiderma from the fruits of hawthorn (54670) have also been reported.
Gastrointestinal ...Orally, rare abdominal discomfort of uncertain relationship to hawthorn has been reported in a large clinical trial, surveillance study, case reports, and a literature review (19247,54640,54692,113112). Digestive intolerance (19241), diarrhea (19243,113112), flatulence (8281), gastroenteritis (8281), increased bowel movements (19243), obstipation (8281), mild and rare nausea (10144,19247,19244), vomiting (113112), nutritional and metabolic problems (17203), and other non-specific gastrointestinal effects (19222), have also been reported. Furthermore, gastrointestinal hemorrhage has been reported in two patients with CHF in a literature review of 5,577 patients (19247).
Musculoskeletal ...In clinical trials, arthritis (8281), back pain (8281), weakness (19243), and other non-specific musculoskeletal effects (19222) have been reported following the use of various hawthorn preparations g. WS 1442, CKBM-A01). Additionally, in a case report, myalgia has been reported following use of hawthorn root extract (113113).
Neurologic/CNS ...Orally, headache and dizziness/vertigo were reported in 2 patients in a large surveillance trial of 3,664 patients with cardiac failure (54692), in 15 patients with CHF as reported in a literature review of 5,577 patients (19247), in a varying number of clinical trial participants (8281,19222,19244), and in case reports (113112,113113). Incidences of fainting (19222), fever (17203), and infrequent, mild and transient sleepiness have also been reported (19221,54692).
Psychiatric ...Orally, agitation was reported in a large surveillance trial of 3,664 patients with cardiac failure (54692).
Pulmonary/Respiratory ...Orally, bronchitis has been reported following the use of hawthorn extract WS 1442 (8281), and bradypnea has been reported following the use of hawthorn root extract (113112).
Renal ...A case of multiorgan hypersensitivity reaction and acute renal failure following the consumption of C. orientalis has been reported (54654).
Other ...Flu-like syndrome (8281) and other non-specific infections have been reported following the use of the hawthorn extract WS 1442 (17203,19222). Hawthorn has also been reported to cause nosebleeds (8281,10144).
