The bottom line No known interaction

We found no known interaction between Danshen and Bentoquatam 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.

Danshen and Bentoquatam

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 Bentoquatam and Danshen 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 Bentoquatam

Interactions in our licensed database are recorded against drug classes, not just single drug names. Bentoquatam is filed under a single classification — topical drugs. Danshen has documented interactions with 16 drug classes — the most serious being anticoagulant/antiplatelet drugs (major), digoxin (lanoxin) (major) and amlodipine (norvasc) (moderate) — and none of Bentoquatam’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.

Keep it in perspective

If something new turns up after you add Danshen, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

Everything above comes from the Natural Medicines adverse-effect record for Danshen — expand a row for the licensed statement it rests on. We haven’t matched Bentoquatam to its FDA label in our system yet, so we can’t compare its own side-effect list here — the leaflet that comes with your prescription is the authoritative list for Bentoquatam.

See Every Supplement That Interacts With Bentoquatam

This page covers Danshen only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Bentoquatam page lists 3 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Dimethylsulfoxide (dmso) (moderate), Turpentine Oil (moderate) and Alchemilla (minor).

From our pharmacist’s overview on the Bentoquatam page

“Bentoquatam (Ivy Block) is a barrier cream applied before outdoor work to keep poison ivy, oak, and sumac oils off the skin, and only three supplement ingredients interact with it on file, all of them other topical products. None rate major.”

About Danshen

What is Danshen?

Danshen
  • Heart and circulation support
  • Angina (chest pain)
  • High blood pressure
  • Anxiety and stress
  • Liver health

Danshen is a root used in traditional Chinese medicine, mainly for heart and circulation problems. Some early research is promising, but the evidence is not strong enough to confirm it works for any condition, and it may affect blood clotting. Talk to a pharmacist or doctor before using it, especially if you take other medicines or have a health condition.

Salvia miltiorrhiza · Lamiaceae · Root · Capsules, tablets, dried root, teas, tinctures, and injectable forms used in some Asian countries

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

Danshen: dosing

There is no well-established standard dose of Danshen for any condition. Studies have used different forms, strengths, and preparations, which makes it hard to recommend a single dose.If you choose to use a Danshen product, follow the directions on the product label and do not take more than recommended.
