Drug & supplement interaction

Jiaogulan + Finasteride

Finasteride brand names: Propecia, Proscar.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Jiaogulan and Finasteride 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

Jiaogulan and Finasteride

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 Finasteride and Jiaogulan 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.

Jiaogulan safety at a glance

Jiaogulan overall Use caution Generally well tolerated in tea or supplement form for short periods, but long-term safety is not well studied.
Pregnancy Possibly Unsafe When used orally. Ginsenoside Rb1, which is identical to the jiaogulan constituent gypenoside 3, has teratogenic effects in animal models; avoid using. Read the full pregnancy detail
Breastfeeding Avoid Avoid while breastfeeding because there is not enough safety information.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Finasteride

Interactions in our licensed database are recorded against drug classes, not just single drug names. Finasteride is filed under 3 classifications — including cytochrome p450 3a4 (cyp3a4) substrates, oral drugs. Jiaogulan has documented interactions with 3 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and immunosuppressants (moderate) — and none of Finasteride’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.

No Interaction Found — But Data Suggests Jiaogulan and Finasteride 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.

Overlapping uses

What Finasteride Is Prescribed For, and What Jiaogulan Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Finasteride is a prescription medicine with approved uses on its FDA label. Jiaogulan is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Finasteride is prescribed for: Finasteride tablets (including the brand Proscar) are used in men with an enlarged prostate (benign prostatic hyperplasia, or BPH) to improve urinary symptoms, lower the risk of acute urinary retention (a sudden inability to urinate), and reduce the need for prostate surgery. Finasteride tablets may also be used alongside the alpha-blocker doxazosin to slow the progression of BPH symptoms. Propecia (and finasteride 1 mg coated tablets) is indicated for the treatment of male pattern hair loss (androgenetic alopecia) in men only. Propecia is not approved for use in women, and its effectiveness for hair loss at the temples has not been established.

Finasteride is not approved for the prevention of prostate cancer.

Jiaogulan has been studied for:

  • Cancer studied, not established Jiaogulan has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Jiaogulan for cancer

    Although there has been interest in using oral jiaogulan for preventing or treating cancer, there is insufficient reliable information about the clinical effects of jiaogulan for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Finasteride on your own; if you are taking Jiaogulan for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

The most serious there right now: Activated Charcoal (major), Grapefruit (major), St. John's Wort (major), Acacia Rigidula (moderate) and Adrafinil (moderate).

By severity: 3 major · 94 moderate · 41 minor.

From our pharmacist’s overview on the Finasteride page

“The supplement list for finasteride (Propecia, Proscar) is one I would read carefully rather than skim, because three of its 138 entries are rated major. Almost everything here works through the same liver enzyme, CYP3A4, that clears finasteride.”

About Jiaogulan

What is Jiaogulan?

Jiaogulan
  • Fatigue and stress (adaptogen)
  • Blood sugar support
  • High blood pressure
  • High cholesterol
  • Immune and general wellness

Jiaogulan is a climbing vine used in traditional Chinese medicine as an adaptogen and for heart, blood sugar, and cholesterol support. Early human and animal studies are promising for some uses like metabolism and blood pressure, but the overall evidence is still limited. Talk with your pharmacist or doctor before starting it, especially if you have a health condition or take medication.

Gynostemma pentaphyllum · Cucurbitaceae · Leaves and aerial parts · Tea, capsules, tablets, liquid extracts, powders

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

Jiaogulan: dosing

There is no official, standardized dose of jiaogulan. The right amount can vary depending on the product, its strength, and whether it is a tea, capsule, or extract.The safest approach is to follow the directions on the product label and not to exceed the recommended amount.

Taking Jiaogulan and Finasteride Together: Common Questions

Is it safe to take Jiaogulan with Finasteride?
We do not list a known interaction between Jiaogulan and Finasteride. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Jiaogulan and Finasteride have any of the same side effects?
Yes — our sources link each of them separately to one of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Are Jiaogulan and Finasteride used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Jiaogulan in each. That is a conversation for your prescriber, especially if Finasteride is being adjusted to a target.
How was the Jiaogulan and Finasteride combination checked?
Interactions in our licensed database are recorded against drug classes. Finasteride is filed under 3 classifications, and Jiaogulan has documented interactions with 3 drug classes — none of Finasteride's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Jiaogulan interact with any other medications?
Yes. Jiaogulan has 327 documented drug interactions in our database — Finasteride is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Finasteride interact with any supplements?
Yes. Finasteride has documented interactions with 138 supplements in our database — Jiaogulan is not one of them. The Finasteride interaction page linked on this page lists every one, ranked by severity.
