Drug & supplement interaction

Butternut + Segesterone Acetate, Ethinyl Estradiol

Segesterone Acetate, Ethinyl Estradiol brand name: Annovera.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Butternut and Segesterone Acetate, Ethinyl Estradiol in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Interaction report

Butternut and Segesterone Acetate, Ethinyl Estradiol

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 Segesterone Acetate, Ethinyl Estradiol and Butternut 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 Segesterone Acetate, Ethinyl Estradiol

No Interaction Found — But Data Suggests Butternut and Segesterone Acetate, Ethinyl Estradiol May Share a Side Effect

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

About Butternut

What is Butternut?

  • Constipation (laxative)
  • Digestive complaints
  • Skin conditions
  • Traditional 'liver' or 'cleansing' remedy
  • Mild laxative in herbal blends

Butternut (Juglans cinerea) is a North American tree whose inner bark was traditionally used as a mild laxative and folk remedy. Modern scientific evidence supporting any of its uses is very limited, and it can cause stomach cramping and other effects, so it should be used cautiously and only with guidance from a healthcare professional.

Juglans cinerea · Juglandaceae · Inner bark (and sometimes nut, leaves, and bark of the root) · Dried bark, tinctures, capsules, and teas

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

Butternut: dosing

There is no well-established or standardized dose for butternut. Traditional preparations varied widely, and the strength of commercial products is not consistent.If you choose to use a butternut product, follow the directions on the label and do not exceed the suggested amount.
