Purple Nut Sedge and Everolimus

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 Everolimus and Purple Nut Sedge 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.

Purple Nut Sedge safety at a glance

Purple Nut Sedge overall Use caution Traditional use is long, but high-quality human safety data are lacking.
Pregnancy Avoid Traditionally used to affect menstruation, so avoid during pregnancy.
Breastfeeding Avoid There is not enough safety information, so it is best avoided.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Everolimus

Interactions in our licensed database are recorded against drug classes, not just single drug names. Everolimus is filed under 7 classifications — including cytochrome p450 2d6 (cyp2d6) inhibitors, cytochrome p450 3a4 (cyp3a4) inhibitors, p-glycoprotein substrates. Purple Nut Sedge has documented interactions with 4 drug classes — the most serious being anticholinergic drugs (moderate), anticoagulant/antiplatelet drugs (moderate) and antidiabetes drugs (moderate) — and none of Everolimus’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

What Everolimus’s Own FDA Label Lists

This is not an interaction — none of it involves Purple Nut Sedge. These are the most notable effects listed in the ADVERSE REACTIONS section of Everolimus’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Dehydration Worth acting on
  • High potassium Worth acting on
  • Low sodium Worth acting on
  • Low blood sugar Worth acting on
  • Low potassium Worth acting on
  • A heart attack Worth acting on
  • Blood clots Worth acting on

From the ADVERSE REACTIONS section of the FDA label for Everolimus. Read the label on DailyMed › Where a percentage is shown, it is the share of 50,590 voluntary FDA FAERS reports for Everolimus that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Purple Nut Sedge’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Purple Nut Sedge side to compare — that is a limit of the record, not a statement that Purple Nut Sedge has no side effects.

See Every Supplement That Interacts With Everolimus

This page covers Purple Nut Sedge only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Everolimus page lists 156 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Asarabacca (major), Grapefruit (major), Siberian Cocklebur (major) and St. John's Wort (major).

By severity: 5 major · 112 moderate · 39 minor.

From our pharmacist’s overview on the Everolimus page

“Everolimus (Afinitor, Zortress, Certican) has to stay in a narrow blood-level window, whether you take it after an organ transplant or for cancer, so treat this supplement list with real caution. Most of its 156 interacting ingredients can push those levels up or down, mainly by changing how the CYP3A4 enzyme breaks the drug down.”

About Purple Nut Sedge

What is Purple Nut Sedge?

  • Digestive upset and bloating
  • Menstrual cramps and irregular periods
  • Fever and inflammation
  • Skin and weight-related concerns
  • Antimicrobial uses

Purple nut sedge (Cyperus rotundus) is a common weed whose tubers have a long history in Ayurvedic, Chinese, and other traditional medicine systems, mostly for digestive and menstrual complaints. Modern human evidence is very limited, so its benefits remain unproven. If you want to try it, talk with a pharmacist or doctor first, and avoid it during pregnancy and breastfeeding.

Cyperus rotundus · Cyperaceae · Tubers (rhizomes) and essential oil · Powder, capsules, decoction (tea), essential oil, traditional herbal formulas

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

Purple Nut Sedge: dosing

There is no well-established or standardized dose for purple nut sedge. Traditional preparations vary widely, and the strength of capsules, powders, and oils differs from product to product.If you choose to use it, follow the directions on the product label and start low. A pharmacist can help you review the product and decide whether it is appropriate for you. Do not use the essential oil internally unless directed by a qualified professional.
