Spearmint and Desogestrel, Ethinyl Estradiol

Here is the interaction we found between these two, with the evidence behind it.

Moderate

HEPATOTOXIC DRUGS

Why this applies to Desogestrel, Ethinyl Estradiol

Desogestrel, Ethinyl Estradiol falls under HEPATOTOXIC DRUGS — the group Spearmint interacts with.

Theoretically, high doses of spearmint might increase the risk of liver damage when taken with hepatotoxic drugs.
Animal research suggests that drinking spearmint tea for 30 days can increase markers of liver damage, including aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and cause liver degeneration and necrosis, in a dose-dependent manner. This effect has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the honest picture: your birth control pill (desogestrel with ethinyl estradiol) is processed through your liver, and so is spearmint. The concern on file is purely theoretical. In one animal study, very large amounts of spearmint tea taken daily for a month nudged up liver enzymes (AST and ALT) and stressed the liver. That has never been shown in people, and it has nothing to do with making your pill stronger or weaker.

For everyday spearmint in food or a cup of tea, this is really not something to lose sleep over. If you're considering a concentrated spearmint supplement, especially alongside any medicine that taxes the liver, just run it by your pharmacist or doctor first so they can keep an eye on things.

About Spearmint

What is Spearmint?

Spearmint
  • Digestive upset and indigestion

  • Hormonal acne and unwanted hair (PCOS-related)
  • Memory and focus
  • Mild stress and anxiety
  • Joint discomfort

Spearmint is a common culinary mint that is generally safe in food and tea amounts.

Talk to your pharmacist or doctor before using concentrated supplements, especially if you are pregnant or have a health condition.
