Interaction report

Japanese Persimmon and Gemcitabine

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 Gemcitabine and Japanese Persimmon 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.

Japanese Persimmon safety at a glance

Japanese Persimmon overall Use caution The fruit is safe as food, but eating large amounts of unripe persimmons may cause hard masses (bezoars) in the stomach.

Pregnancy Use caution Eating the fruit as food is likely fine, but concentrated leaf or calyx supplements have not been well studied, so avoid those.

Breastfeeding Use caution The fruit as food is likely fine, but there is not enough data on concentrated supplements, so use caution.

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

How we checked

Why No Interaction Is Listed for Gemcitabine

Interactions in our licensed database are recorded against drug classes, not just single drug names. Gemcitabine is filed under 2 classifications — antineoplastics, hepatotoxic drugs. Japanese Persimmon has documented interactions with 2 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate) and antihypertensive drugs (moderate) — and none of Gemcitabine’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 to actually watch for

What Gemcitabine’s Own FDA Label Lists

This is not an interaction — none of it involves Japanese Persimmon. These are the most notable effects listed in the ADVERSE REACTIONS section of Gemcitabine’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.

A stroke or mini-stroke Worth acting on
A heart attack Worth acting on
A low platelet count Worth acting on mentioned in 7.0% of FDA reports for Gemcitabine
An irregular heartbeat Worth acting on
Anemia Worth acting on mentioned in 5.8% of FDA reports for Gemcitabine
A low white blood cell count Worth acting on mentioned in 6.2% of FDA reports for Gemcitabine
Kidney problems Worth acting on
Raised blood pressure Worth acting on
Shortness of breath Worth acting on
Liver problems Worth acting on

Showing the 10 most notable of 16 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Gemcitabine. Read the label on DailyMed › Where a percentage is shown, it is the share of 53,020 voluntary FDA FAERS reports for Gemcitabine that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Japanese Persimmon’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Japanese Persimmon side to compare — that is a limit of the record, not a statement that Japanese Persimmon has no side effects.

About Japanese Persimmon

What is Japanese Persimmon?

High blood pressure
Cough and hiccups (traditional use)
Antioxidant support
Digestive health and fiber
Skin and general wellness

Japanese persimmon is a nutritious fruit rich in fiber, vitamins, and antioxidant plant compounds, and its leaves and calyx are used in traditional medicine. While eating the fruit as food is generally safe and healthy, the evidence for concentrated supplements or leaf extracts treating specific conditions is limited. Talk to your pharmacist or doctor before using persimmon products medicinally.

Diospyros kaki · Ebenaceae · Fruit, leaves, and the dried fruit calyx (persimmon stalk) · Fresh or dried fruit, tea (often from leaves), powder, capsules, and extracts

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

Japanese Persimmon: dosing

There is no standardized or proven medicinal dose for persimmon supplements. As a food, persimmon is simply eaten as a fresh or dried fruit. For leaf teas, powders, and capsules, the right amount varies by product.If you choose to use a persimmon supplement, follow the directions on the product label and do not exceed the recommended amount.
