The European chestnut (Castanea sativa), also known as the sweet chestnut, is a species of flowering plant in the family Fagaceae, native to Europe and Asia Minor, and widely cultivated throughout the temperate world. The tree attains a height of 100 feet (30 m). It has rugged, grooved bark and glossy, serrate, oblong-lanceolate leaves up to 11 inches (28 cm) in length.

Ok, mix that with some honey, onion extract .... sounds like the old alchemist may have been ahead of their times.

Silver Sol works too.

Excellent. I figured it was only a matter of time.

Sure makes you think about clearing the rain forest and things like that.

Chestnuts were widespread here. Then the blight killed most of them.

[[Rather than killing Staphylococcus aureus, the chestnut leaf extract — rich in oleanene and ursene derivatives (pentacyclic triterpenes) — works by taking away bacteria’s weapons, essentially shutting off the ability of the bacteria to create toxins that cause tissue damage.]]

Ok fine- but now we’ve got staph lying dormant in our bodies? What happens when the extract is stopped?

[Bob434]

if you’re talking about colloidal silver- watch out- it can and has turned people’s skin a real ugly blue- permanetly

Thanks! Nice find.

That would be the American Chestnut. The European Chestnut is another species.

Silver Sol is a nano silver. We used the gel on my mother when she had an acute case of MRSA. The doctors were astonished it healed. We used the gel liberally, but it got the job done. She also was on antibiotics.

Great for more superficial stuff but doesn’t work on deep tissue infections like I’ve had. No topical formulation does. Silver taken orally is worthless.

Ping! (MRSA)

The MRSA infection was to the bone.

We had a lot of people praying for her.

We had a lot of people praying for her.

Which is probably the correct explanation for the recovery.

It's well known that Copper and Silver have antimicrobial properties (in particular, silver is widely used in dressings of wounds when antibiotics are counter-indicated or not effective) but their uses have certain side effects and are limited mostly to contact surface of skin and wound, and they are expensive, while this chestnut extract could be synthesized and cheaply made, and safely used with disinfectants as well as applied directly to patients.

[[— works by taking away bacteria’s weapons, essentially shutting off the ability of the bacteria to create toxins that cause tissue damage.]]

The presumption is that the biochemical change of bacteria is permanent or long-lasting enough, when it no longer poses a serious threat to a healthy immune system. In which case the "dormant" would not really be the proper adjective anymore. There are plenty of harmless and even useful bacteria and viruses in human bodies.

[[The extract does not lose activity, or become resistant, even after two weeks of repeated exposure.]]
