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 Fo-ti and Mineral Oil 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 label for Mineral Oil states a food rule worth keeping to.

Fo-ti and Mineral Oil

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 Mineral Oil and Fo-ti 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 Mineral Oil

Interactions in our licensed database are recorded against drug classes, not just single drug names. Mineral Oil is filed under a single classification — oral drugs. Fo-ti has documented interactions with 17 drug classes — the most serious being anticoagulant/antiplatelet drugs (moderate), antidiabetes drugs (moderate) and contraceptive drugs (moderate) — and none of Mineral Oil’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 Fo-ti Itself Has Been Linked To

This is not an interaction — nothing below involves Mineral Oil. It is the side-effect record for Fo-ti on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Fo-ti, this list is the first place to look. 2 entries are worth acting on rather than waiting out — marked below.

  • Yellowing of the skin or eyes / A low platelet count Worth acting on Additional detail

    “Orally, cases of liver damage due to both processed and unprocessed fo-ti have been well documented in the medical literature..

    In a systematic review, around 450 cases of hepatitis associated with fo-ti were identified. These cases occurred in patients 5-78 years of age. Liver damage occurred at a wide range of doses, formulations, and durations of intake.”

Special populations

Fo-ti in Pregnancy & Breastfeeding

Pregnancy Possibly Unsafe

When used orally. Fo-ti contains anthraquinone constituents, which can exert a stimulant laxative effect. Bulk-forming or emollient laxatives are preferred in pregnancy. Fo-ti has also been linked to several cases of liver damage. There is insufficient reliable information available about the safety of fo-ti when used topically during pregnancy.

Lactation Possibly Unsafe

When used orally. Anthraquinone constituents can cross into breast milk and might cause loose stools in some breast-fed infants. Fo-ti has also been linked to several cases of liver damage. There is insufficient reliable information available about the safety of fo-ti when used topically during lactation.

How to take them

Some Mineral Oil Products Have a Food Rule — Fo-ti Should Not Break It

At least one FDA label for a product containing Mineral Oil says to take it with food. If you take Fo-ti on an empty stomach out of habit, keep them separate — and take Mineral Oil with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Mineral Oil products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

Directions: * Do not take with meals.

From the Dosage and Administration section of the FDA label we read for Mineral Oil — where that label names a specific product, the instruction is that product's. See the Mineral Oil drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Everything else you take

See Every Supplement That Interacts With Mineral Oil

This page covers Fo-ti only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Mineral Oil page lists 17 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Coffee Charcoal (moderate), European Mandrake (moderate), Glucomannan (moderate) and Guar Gum (moderate).

By severity: 1 major · 7 moderate · 9 minor.

From our pharmacist’s overview on the Mineral Oil page

“Everything on record for mineral oil (Kondremul Plain) comes down to one theme, absorption in the gut, and it deserves genuine care, chiefly because of activated charcoal. Charcoal binds a wide array of medicines and can sharply cut how much of them the body actually takes in, and it carries this list's only major rating, so understand…”

About Fo-ti

What is Fo-ti?

  • Anti-aging and longevity
  • Hair graying and hair loss
  • General tonic for vitality
  • Constipation
  • High cholesterol

Fo-ti (He Shou Wu) is a root used in traditional Chinese medicine, often promoted for healthy aging and hair. High-quality human evidence for these benefits is limited, and processed Fo-ti has been linked to reports of liver injury, so caution and professional guidance are important.

Reynoutria multiflora · Polygonaceae · Root (often prepared/processed) · Capsules, tablets, dried root, tea, tinctures, powders

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

Fo-ti: dosing

There is no well-established, standardized dose of Fo-ti, and products vary widely in strength and preparation (raw versus prepared root). Because of this and the liver concerns, it is best not to guess at an amount on your own.If you choose to use it, follow the directions on the product label and do not exceed them.

Humco Mineral Oil Light topical liquid is used to help treat and prevent diaper rash, protect chafed skin, and seal out wetness. HANHOO BlemishPatch is applied directly to skin concerns as a topical patch.

Taking Fo-ti and Mineral Oil Together: Common Questions

Is it safe to take Fo-ti with Mineral Oil?
We do not list a known interaction between Fo-ti and Mineral Oil. 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.
Should I take Fo-ti and Mineral Oil at the same time of day?
At least one FDA label for a product containing Mineral Oil says to take it with food. If you take Fo-ti on an empty stomach out of habit, keep them separate and take Mineral Oil with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Mineral Oil products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Fo-ti and Mineral Oil combination checked?
Interactions in our licensed database are recorded against drug classes. Mineral Oil is filed under 1 classification, and Fo-ti has documented interactions with 17 drug classes — none of Mineral Oil'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 Fo-ti interact with any other medications?
Yes. Fo-ti has 1,257 documented drug interactions in our database — Mineral Oil 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 Mineral Oil interact with any supplements?
Yes. Mineral Oil has documented interactions with 17 supplements in our database — Fo-ti is not one of them. The Mineral Oil interaction page linked on this page lists every one, ranked by severity.
