The bottom line No known interaction

We found no known interaction between Yin Chen and Propranolol 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.

Yin Chen and Propranolol

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 Propranolol and Yin Chen 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.

Yin Chen safety at a glance

Yin Chen overall Use caution Generally used in traditional medicine, but human safety data are limited.
Pregnancy Avoid Not enough safety information; Artemisia plants are best avoided during pregnancy.
Breastfeeding Avoid No reliable safety data, so avoid use while breastfeeding.

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

How we checked

Why No Interaction Is Listed for Propranolol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Propranolol is filed under 9 classifications — including beta-blockers, cytochrome p450 2c19 (cyp2c19) substrates, antihypertensive drugs. Yin Chen has documented interactions with 2 drug classes — the most serious being cns depressants (moderate) and pentobarbital (nembutal) (moderate) — and none of Propranolol’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 Yin Chen Itself Has Been Linked To

This is not an interaction — nothing below involves Propranolol. It is the side-effect record for Yin Chen on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Yin Chen, this list is the first place to look. 3 entries are worth acting on rather than waiting out — marked below.

  • Fainting Worth acting on Additional detail

    “Orally, yin chen has been reported to cause dizziness. Taking yin chen in doses of 15-30 grams has been reported to cause headache, numbness and tremor of the upper extremities, and fainting (12).”

  • Liver problems Worth acting on Additional detail

    “Orally, taking yin chen in doses of 15-30 grams has been reported to cause arrhythmias (12). In one study, two females taking yin chen and da zao (Fructus Zizyphi Jujubae) orally to treat infectious hepatitis developed Adams-Stokes syndrome (sudden collapse into unconsciousness due to serious arrhythmias). It is not clear if yin chen, da zao, the combination, or another factor was responsible.”

Everything above comes from the Natural Medicines adverse-effect record for Yin Chen — expand a row for the licensed statement it rests on. We haven’t matched Propranolol 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 Propranolol.

Everything else you take

See Every Supplement That Interacts With Propranolol

This page covers Yin Chen only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Propranolol page lists 236 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), American Hellebore (major), American Mistletoe (major), Indian Snakeroot (major) and Tyramine (major).

By severity: 5 major · 194 moderate · 37 minor.

From our pharmacist’s overview on the Propranolol page

“Propranolol (Inderal) slows the heart and lowers blood pressure, which is exactly why its 236-ingredient interaction list deserves genuine care. Five entries rate major, and those are the ones to understand first.”

About Yin Chen

What is Yin Chen?

Yin Chen
  • Liver and gallbladder support
  • Jaundice (traditional use)
  • Digestive complaints
  • Skin conditions (topical)
  • Anti-inflammatory and antimicrobial purposes

Yin Chen is a traditional Chinese medicine herb used mainly for liver and gallbladder complaints and jaundice. Most of the evidence comes from laboratory and animal studies, so its benefits in people are not well proven. Talk with a pharmacist or doctor before using it, especially if you have a liver condition, are pregnant, or are breastfeeding.

Artemisia capillaris · Asteraceae · Aerial parts (young shoots and leaves) · Tea, dried herb, powdered extract, capsules, topical washes, and traditional herbal formulas (such as Inchinko-to/Yin Chen Hao Tang)

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

Yin Chen: dosing

There is no well-established, standardized dose of Yin Chen for any condition. Traditional preparations and modern products vary widely in strength and form.If you choose to use it, follow the directions on the product label and do not exceed them. Avoid guessing your own dose.

About Propranolol (Cardiovascular)

What Is Propranolol (Cardiovascular) Used For?

Brand names: Inderal LA, Inderal, Angilol, Syprol, Inderal Injection, Half-Inderal LA, Bedranol SR, Half Beta Prograne, Beta Prograne, Lopranol LA, Slo-Pro, InnoPran XL

This intravenous (IV) form of propranolol is used in hospital or clinical settings to treat dangerous heart rhythm problems. It is generally reserved for life-threatening arrhythmias (abnormal heart rhythms) or those that occur during anesthesia.

Specific conditions it treats include fast heart rates coming from the upper chambers of the heart (supraventricular tachycardia), certain arrhythmias caused by digitalis toxicity, dangerous ventricular rhythms that haven't responded to other treatments, and fast heart rates caused by excess adrenaline-like substances during surgery.
