Tinctures of propolis - expiry?

by Deanna
(Louisiana)

I just found your website and would like to know what is the average shelf life of tincture of propolis? Does it every "go bad"? I've read that it has natural antioxidant and antimicrobial properties but wonder if it still can be contaminated over time by bacteria. How long will it remain safe to use?

Angela's Comments:

Hi Deanna,
You are correct in that propolis is loaded with natural antioxidants and will self preserve so to speak. An alcohol based tincture will last several years as the alcohol helps preserve it further. We recommend our water based tinctures to be used within two years for maximum freshness.

Hope that helps,
Angela

Propolis tincture expiration?

by Doug
(Seattle)

I understand that dry forms of propolis would lose potency after a year, but I'm wondering if tincture forms would ever really expire. The ethanol solution they're in is very stable, of course.

Does anyone have a suggestion or reference regarding this?

Of course the bottles list expirations. They always do. But it's a well known fact that many medicines essentially never lose potency even though they have expirations listed.


Angela's comments:

Hi Doug,
You are correct. In an ethanol base, the tincture will last for years.

Propolis powder use after expiration date

How long does propolis powder last after expiration date?

Angela's Comments:

It really depends on a number of factors. Was it stored in a cool, dry place? And also was the bottle opened? Propolis is very high in anti-oxidants so it should last well past the stated best before date if kept dry and cool. If the bottle is unopened, this also should help extend the best before date.

Are there any signs of rancidity or spoilage? If not, you just might be ok to consume it.

Bee healthy,
Angela

Propolis expiration

hi, I have a chunk of raw propolis that I got from my dad (who was a bee keeper) over 7 years ago. It's been kept in the fridge all this time. Does it still have any power?
thanks,

Is my propolis expired?

by Larry

I have a propolis paste for 20 years.
It has been kept at room temperature.
It smells the same as the day I purchased it.
Is it still good to use on the skin?
Is it useful in the treatment of shingles?

Angela's Comments:

Hard to say Larry but I would err on the side of caution and say no.
