Blackberry leaves, blackthorn berries, linden flower, or rowanberry tea for brain fog?

I think it would be difficult without lab testing. There are numerous flavonoids and other phenolic compounds that hypothetically could be relevant. Ruling out ingredients based on blends doesn't account for the differences in processing etc. Who knows what is really there without testing?

For example, rosehips are high in quercetin, but it has very low oral bioavailability. Ellagic Acid is likewise common in these sources. Urolithins (ellagic acid metabolites) and quercetin are considered phytoestrogens but their biological activity is not well characterised in humans.

Yeah I’ve basically given up trying to figure out the exact compound. Even the ones that are unique to some of the ingredients don’t have much particularly useful information on why they might be helpful.

I’m hoping I can just narrow down the ingredient that’s helpful

I still wonder if it could be the peppermint. For something else, I put some peppermint oil in a humidifier and it seemed to have an effect on brain fog. N=1 of course.

That’s interesting! I have other blends with even higher percentage of peppermint and don’t get a similar effect, so I’m inclined to think it’s not peppermint in my case. Though as Mij suggested it might be a combination of peppermint with something else

Today I read that tea can be brewed from yaupon bushes, a type of holly native to the Texas Hill Country and other areas of the American South. We have a lot on our property.

It's the only American plant with caffeine, and, from what I've read, it has about 1/3 of the caffeine as a cup of coffee. It contains more theobromine and theophylline than coffee or regular tea. The combination of these 2 compounds is supposed to make the caffeine in yaupon tea feel smoother and more gradual. Yaupon also has antioxidants and polyphenols and is low in tannins.

I ordered a small bag of loose-leaf yaupon tea from Catspring. It seems worth a try. Here's a BBC article about yaupons and yaupon tea that details its interesting history.

Yaupon: The rebirth of America's forgotten tea

It is North America's only known native caffeinated plant and once threatened the British East India Company. So why has the world forgotten about it?

I’ve never heard of it, that’s so interesting! Thanks for the link
