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 the fruit is used orally and appropriately. A specific brand of pagoda tree fruit extract (Rexflavone, Rexgene Biotech Co. Ltd.) has been used safely in doses of up to 350 mg daily for up to 12 weeks (99966).
POSSIBLY UNSAFE ...when the seeds are used orally (18). Regular use of seed meal can cause facial edema or even death (18).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when the seed is used orally (18); avoid using.
There is insufficient reliable information available about the safety of the fruit when used orally during pregnancy or lactation.
POSSIBLY SAFE ...when used orally and appropriately. White mulberry powdered leaf or leaf extract has been used with apparent safety at doses of up to 4.6 grams three times daily for up to 12 weeks (16494,17051,100627,103870,105796,110480). There is insufficient reliable information available about the safety of white mulberry berries.

Theoretically, pagoda tree might reduce the clearance of caffeine.
 Details
Pagoda tree contains genistein. Taking genistein 1 gram daily for 14 days seems to inhibit caffeine clearance and metabolism in healthy females (23582). This effect has been attributed to inhibition of the cytochrome P450 1A2 (CYP1A2) enzyme, which is involved in caffeine metabolism. It is unclear if this effect occurs with the lower amounts of genistein found in pagoda tree.

Theoretically, white mulberry leaf might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
|
Theoretically, white mulberry leaf might slow the elimination and increase the adverse effects of drugs which are OCT2 substrates.
Details
Animal research shows that coadministration of white mulberry leaf extract with metformin, an OCT2 substrate, slows the renal elimination of metformin via inhibition of OCT2 activity (103869). OCT2 is expressed in the kidneys and is responsible for transporting cationic drugs into tubular epithelial cells in order to be excreted in the urine.

General
...Orally, pagoda tree flower and fruit seem to be well tolerated.
No adverse effects have been reported; however, a thorough evaluation of safety outcomes has not been conducted. The pagoda tree seed is possibly unsafe when consumed long-term.
Serious Adverse Effects (Rare):
Orally: With use of the seed, death and edema.
Other ...Orally, using pagoda tree seed long-term may cause edema and death (18).
General
...Orally, white mulberry leaf seems to be well tolerated.
Most Common Adverse Effects:
Orally: Transient bloating, constipation, flatulence, and loose stools.
Gastrointestinal ...Orally, white mulberry leaf powder 4. 6 grams three times daily for 4 weeks was associated with bloating and flatulence in 50% of patients, loose stools in 25% of patients, and constipation in 21% of patients in one clinical study. However, reports of these adverse effects decreased over the course of the 12-week study, suggesting that for some patients the adverse effects may be transient in nature (103870).
