European Mandrake and Clomiphene

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the basic idea with European mandrake and Clomid (clomiphene). Mandrake's tropane alkaloids slow down how fast your gut moves things along. When food and pills sit in your digestive tract longer, your body can sometimes absorb a bit more of a swallowed medication. So in theory, this could nudge up how much clomiphene gets into your system, which might mean a stronger effect or more of its usual side effects, like hot flashes, bloating, mood swings, or blurred vision.

I want to be honest with you though: this is a theoretical concern based on how these chemicals work, not something well documented in real patients. The bigger issue is that mandrake is genuinely poisonous, and I'd urge you not to take it at all. Please run any combination by your pharmacist or doctor first.

From our pharmacist’s overview on the Clomiphene page

“Clomiphene (Clomid, Serophene) is taken as a short, precisely timed course to trigger ovulation, so anything that weakens a dose can cost someone trying to conceive a whole cycle. That is why the 17 supplements listed here deserve genuine care, since every one of them can change how much of the pill the gut actually absorbs.”

About European Mandrake

What is European Mandrake?

European Mandrake
  • Insomnia (traditional)
  • Pain relief (historical)
  • Anxiety or depression (folk use)
  • Gout and aches (traditional)
  • Sedation or anesthesia (historical)

European mandrake is a highly toxic plant from the nightshade family that was used in ancient and medieval times as a sedative and pain reliever. It contains powerful poisons that can cause serious harm or death, and there is no proof it safely treats any condition. We strongly recommend you do not consume mandrake in any form.

About Clomiphene

What Is Clomiphene Used For?

Brand names: Serophene, Clomid

Clomiphene tablets are indicated for women who are not ovulating normally and want to become pregnant. It is most likely to help women with polycystic ovary syndrome (PCOS), amenorrhea-galactorrhea syndrome, psychogenic amenorrhea, post-oral-contraceptive amenorrhea, and certain cases of secondary amenorrhea (absent periods of unknown cause).

Before starting treatment, other barriers to pregnancy — such as thyroid disorders, adrenal disorders, high prolactin levels, or male factor infertility — must be ruled out or treated. Clomiphene is not recommended for use in combination with other ovulation-inducing drugs or for IVF programs, and it is not approved for treating male infertility.
