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.

Theoretically, guar gum might reduce the absorption of ethinyl estradiol, potentially decreasing its effectiveness.
Details
Animal research shows that taking guar gum with ethinyl estradiol decreases ethinyl estradiol absorption (12421). However, this effect has not been reported in humans.

Guar gum might reduce the absorption of metformin, potentially decreasing its effectiveness.
Details

Guar gum might reduce the absorption of some oral drugs, potentially decreasing their effectiveness.
Details
|
Guar gum might reduce the absorption of penicillin, potentially decreasing its effectiveness.
Details
A small clinical study in healthy volunteers shows that taking guar gum with penicillin results in decreased penicillin absorption and reduced penicillin levels (533).

General
...Orally, guar gum is generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, bloating, diarrhea, flatulence, heartburn, gas, and loose stools.
Serious Adverse Effects (Rare):
Orally: Severe esophageal and small bowel obstruction when taken with an inadequate amount of fluid.
Gastrointestinal
...Orally, guar gum may cause gastrointestinal adverse effects such as abdominal cramps, abdominal pain, bloating, diarrhea, flatulence, heartburn, gas, and loose stools (10896,10897,12541,12543,12545,12547,12548,54209,54212,54232)(54260,54314,54333,93617,93619).
Gastrointestinal side effects can be minimized by starting with small doses and titrating up. In one clinical study, taste aversion to guar gum leading to withdrawal from the study has been reported (16736).
When guar gum is consumed with inadequate amounts of fluids, it can cause severe esophageal and small bowel obstruction. Tell patients to take guar gum with at least 8 ounces (250 mL) of water (602,54230).
Pulmonary/Respiratory ...Occupational exposure to guar gum may cause asthma (600,601).
