Carqueja and Diethylstilbestrol, Methyltestosterone

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Diethylstilbestrol, Methyltestosterone and Carqueja in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

How we checked

Why No Interaction Is Listed for Diethylstilbestrol, Methyltestosterone

Interactions in our licensed database are recorded against drug classes, not just single drug names. Diethylstilbestrol, Methyltestosterone is filed under 4 classifications — including testosterone, androgens, hepatotoxic drugs. Carqueja has documented interactions with 1 drug class — the most serious being antidiabetes drugs (moderate) — and none of Diethylstilbestrol, Methyltestosterone’s classifications are among them.

From our pharmacist’s overview on the Diethylstilbestrol, Methyltestosterone page

“Tylosterone pairs diethylstilbestrol, an estrogen, with methyltestosterone, an oral androgen already known for stressing the liver, and that is exactly where this interaction list concentrates. I would handle these 73 supplements carefully.”

About Carqueja

What is Carqueja?

  • Digestive upset and bloating
  • Liver and gallbladder support
  • Blood sugar control
  • Weight loss
  • Anti-inflammatory

Carqueja is a South American herb traditionally used as a bitter tea for digestion, liver complaints, and blood sugar. Human evidence is very limited, so its benefits are not well proven. Because safety data are thin, it should be avoided in pregnancy and breastfeeding and used cautiously by everyone else.

Baccharis trimera · Asteraceae · Aerial parts (stems and winged branches) · Tea (infusion or decoction), tincture, capsules, liquid extract

An interaction check asks whether these two react with each other — it does not ask whether Carqueja is a good idea for someone in your situation. Here is what our Carqueja record says about it on its own.

Carqueja: dosing

There is no well-established standardized dose for carqueja. Traditional use is most often as a tea made from the dried aerial parts, but the strength of teas, tinctures, and capsules varies widely between products.The safest approach is to follow the directions on the product label and not exceed the suggested amount.
