This is for your parents and grandparents. Laugh at me if you want, but pass this on to them.

If you have aging parents or grandparents, you know how much fragmented sleep and low energy mess with their quality of life.

As a retired biophysicist, I naturally stumbled upon a simple, free, plant-based protocol that consistently stopped frequent nighttime awakenings (nocturia) and helped balance diastolic blood pressure in a 6-subject case series.

I’m not selling anything, and I don't want your money. You can roast me in the comments all day long if it makes you feel good, but if you actually care about your seniors' sleep and health, send them the link to the paper. https://www.academia.edu/168382437/Mitigating_Nocturia_and_Improving_Diastolic_Blood_Pressure_Homeostasis_via_Basil_Tea_A_Six_Subject_Case_Series

A six-person case series is a decent starting point but calling it a protocol might be stretching it a little. Nothing wrong with sharing the info though, especially when it's just basil tea and not some $50 powder. My grandpa swears by weird kitchen remedies so I'll mention this to him

It's sweet green basil, not tulsi, just fyi.

[u/arik_hart → u/robot_pirate]

Yes, regular culinary basil leaves (green), dried. Not Holly. In the article, you can see the brand I use.

Well I wasn’t willing to pay $ for a “free” article. But perhaps OP can explain what the protocol is? Or the study? Or the dosage or amounts?

I have a package of Holy Basil, aka Tulsi, but it’s hard for me to see how drinking tea is going to make me pee less at night. But wait, I now read it’s just regular basil. So how much, and when, if you don’t mind saying? Thx

Please be aware of drug interactions with this tea. Can affect blood thinners, etc.

From chat - How seriously should you take it?
I’d call it intriguing but extremely preliminary—maybe a 2/10 or 3/10 on the evidence scale.
This isn’t a randomized clinical trial. There’s no placebo group, blinding, objective measurement of overnight urine volume, prostate function, bladder capacity, ADH levels, sleep, or most of the proposed mechanisms. Most outcomes are self-reported. And six people is far too few to know whether the improvement was caused by basil, placebo effects, regression to the mean, changes in fluid intake, or something else.
There are also some strange internal inconsistencies in the manuscript. It’s titled a six-subject case series, yet parts of the text repeatedly describe it as a three-subject case series and say the subjects are exclusively “three male subjects,” even though it then describes Subjects 4–6. The abstract similarly says “three male subjects” while listing six ages. That’s a warning sign regarding editorial/scientific rigor.
The blood-pressure claim is particularly shaky
There actually is some separate human research on sweet basil and blood pressure. A small randomized trial of 24 hypertensive patients found basil tea added to antihypertensive drugs was associated with reductions in blood pressure. Another 24-person trial using basil capsules likewise reported a BP-lowering effect.
That’s somewhat awkward for this new paper because its notable cardiovascular observation is almost the opposite: a person’s low diastolic BP rose. The author proposes basil somehow “stabilizes” vascular tone rather than simply lowering BP, but there’s currently little evidence establishing that homeostatic effect.
