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.

Below is general information about the safety of the known ingredients contained in the product Cosmepro Polygoni Multiflori. 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 UNSAFE ...when used orally. Fo-ti has been linked to several cases of liver damage (7626,7627,14327,14347,14482,16459,17192,50711,50727,50729) (92892,92895,112231).
CHILDREN: POSSIBLY UNSAFE
when used orally.
Fo-ti has been linked to several cases of liver damage in adults and at least one case in a 5-year-old child (14339,92895).
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Fo-ti contains anthraquinone constituents, which can exert a stimulant laxative effect. Bulk-forming or emollient laxatives are preferred in pregnancy (272). Fo-ti has also been linked to several cases of liver damage (7626,7627,14327). There is insufficient reliable information available about the safety of fo-ti when used topically during pregnancy.
LACTATION: POSSIBLY UNSAFE
when used orally.
Anthraquinone constituents can cross into breast milk and might cause loose stools in some breast-fed infants (272). Fo-ti has also been linked to several cases of liver damage (7626,7627,14327). There is insufficient reliable information available about the safety of fo-ti when used topically during lactation.
Below is general information about the interactions of the known ingredients contained in the product Cosmepro Polygoni Multiflori. 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, fo-ti might increase the risk of hypoglycemia when taken with antidiabetes drugs.

Theoretically, taking large amounts of fo-ti might interfere with contraceptive drugs due to competition for estrogen receptors.
Details
|
Theoretically, fo-ti might increase or decrease the levels and clinical effects of drugs metabolized by CYP1A2.
Details
In vitro research suggests that fo-ti might inhibit CYP1A2 (12479,112351). Additionally, in vitro research suggests that the degree of CYP1A2 inhibition depends on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, in an animal study, an aqueous extract of fo-ti inhibited CYP1A2 while an alcoholic extract of fo-ti induced CYP1A2 (92898). Induction or inhibition of CYP1A2 by fo-ti has not been reported in humans.

Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP2B6.
Details
Animal research suggests that fo-ti might inhibit CYP2B6 (92898). One in vitro study suggests that the degree of CYP2B6 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, this interaction has not been reported in humans.

Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2C19.
Details
Animal and in vitro research suggests that fo-ti may inhibit CYP2C19 (12479,92898,112351). An in vitro study suggests that the degree of CYP2C19 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, this interaction has not been reported in humans.

Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2D6.
Details
Animal research suggests that fo-ti might inhibit CYP2D6 (92898). Additionally, an in vitro study suggests that the degree of CYP2D6 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, this interaction has not been reported in humans.

Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP3A4.
Details
In vitro research suggests that fo-ti might inhibit CYP3A4 (12479,112351). One in vitro study suggests that the degree of CYP3A4 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts) (112351). However, this evidence conflicts with animal research suggesting that fo-ti does not inhibit CYP3A4 (92898). This interaction has not been reported in humans.

Theoretically, fo-ti might increase or decrease the levels and clinical effects of sulindac.
Details
Animal research suggests that the type of fo-ti extract might affect the levels of sulindac differently; the raw plant may increase levels, but processed parts may decrease levels (112351). Induction or inhibition of CYP1A2 by fo-ti has not been reported in humans.

Theoretically, fo-ti might increase the effects and adverse effects of warfarin.
Details
Fo-ti may have stimulant laxative effects and cause diarrhea, especially when the raw or unprocessed fo-ti root is used (5,12,16459,50733,99855). Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Also, fo-ti has been linked to cases of acute liver failure which can decrease clotting factor production and increase the effects of warfarin. In one case, a patient who had been stable on warfarin presented with acute hepatitis and an INR elevated to 14.98. The patient had been taking fo-ti for 90 days prior to admission. Discontinuation of warfarin and fo-ti lead to a decrease in the INR and full recovery (17192).

Below is general information about the adverse effects of the known ingredients contained in the product Cosmepro Polygoni Multiflori. 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, fo-ti may be unsafe.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, nausea, and vomiting with use of unprocessed fo-ti.
Serious Adverse Effects (Rare):
Orally: Hepatotoxicity with processed or unprocessed fo-ti.
Dermatologic ...Orally, one case of a fine maculopapular rash was reported in a patient taking the herbal product known as Shen-Min, which contains fo-ti. Symptoms resolved within three weeks after discontinuing the product (14482). It is unclear if the rash was due to fo-ti or other ingredients in the herbal product.
Gastrointestinal ...Orally, unprocessed fo-ti may cause diarrhea, abdominal pain, nausea, and vomiting (12,50733).
Hematologic ...Orally, one case of mild eosinophilia was reported in a patient taking the herbal product known as Shen-Min, which contains fo-ti. Symptoms resolved within three weeks after discontinuing the product (14482). It is unclear if this reaction was due to fo-ti or other ingredients in the herbal product. A case of agranulocytosis was reported in a 65-year-old female taking fo-ti 30 grams/day for 17 days. The patient recovered gradually following a 15-day hospitalization, which included treatment with intravenous steroids and granulocyte colony-stimulating factor (112231).
Hepatic
...Orally, cases of liver damage due to both processed and unprocessed fo-ti have been well documented in the medical literature.
(7626,7627,14327,14339,14347,14482,16459,17192,50711,50726)(50727,50729,92892,92895,112231).
In a systematic review, around 450 cases of hepatitis associated with fo-ti were identified. These cases occurred in patients 5-78 years of age. Liver damage occurred at a wide range of doses, formulations, and durations of intake. The type of liver injury ranged from hepatocellular, to cholestatic, or mixed. Outcomes ranged from full recovery to cirrhosis, liver transplantation, and/or death. The evidence suggests that when the daily fo-ti dose is less than 12 grams, the median time to occurrence of liver damage is 60 days. When the daily fo-ti dose is more than 12 grams, the median time to liver damage is 30 days (92895). Presenting signs and symptoms may include jaundice, abdominal pain, nausea, fatigue, loss of appetite, dark urine, myalgias, and elevations in liver function tests (LFTs), ferritin, transferrin, prothrombin time, and INR (17192,92892). Other manifestations may include fever, skin rash, thrombocytopenia, pancytopenia, and arthralgias. Symptoms and increased LFTs usually seem to resolve within a month after discontinuing fo-ti (7626,7627,14339,14347,14482,16459). In one case series, liver enzymes began to normalize 48 hours after discontinuation of fo-ti and treatment with S-adenosylmethionine, compound glycyrrhizin injection, polyene phosphatidylcholine, and reduced glutathione. All patients were eventually discharged home in stable condition (92892). Rechallenge with fo-ti should not be attempted. A patient who had recovered from hepatitis associated with fo-ti use presented with myalgias and markedly elevated LFTs after a single dose of the herb (17192).
It is thought that this idiosyncratic reaction leading to liver damage is at least partially related to genetic polymorphisms. Cytochrome P450 1A2 (CYP1A2) is the predominant enzyme involved in biotransformation of emodin, a constituent of fo-ti thought to play a role in liver damage. In one genetic study, the frequency of CYP1A2*1C mutation in fo-ti induced drug-induced liver injury patients was 46.5%, which is significantly higher than the 27.9% frequency of liver injury reported in healthy patients without the mutation. Patients with a CYP1A2*1C mutation may have decreased activity of the CYP1A2 enzyme, which could inhibit the metabolism of fo-ti, causing an accumulation of toxic substances (92897).
