Curry spice turmeric boosts memory by nearly 30%, eases depression, study finds

It's a matter of practicality too. A scientific experiment of any kind can only in full honestly provide a set of results given a set of conditions. No matter how well your theory may fit the existing data, fundamentally your data may simply be responding to some other mechanism you're not aware of or not measuring.

There is a huge amount of effort required to say why something works with certainty. Usually to get there requires many years of experience with a new surprising result. Which requires publishing lots of results before understanding the mechanism.

If you refuse to believe anything that isn't figured out from first principles is true... I mean... I have a condition and if someone told me a higher percentage of patients on a new drug did well than on the one I use, do I care if they can tell me exactly why? Not in the slightest. I will wait a year or two to see if side-effects crop up and ideally see the results confirmed, but I'm not going to not get a treatment likely to help just because they don't know how exactly how it works.

I think it's good practice to assume the results of a paper are accurate, even if you give no credence to the interpretation.

"rigorous" in science, especially biomedical sciences, has a specific definition. Where is the double-blind testing? Where is the statistical significance? Where are the clinical trials?

Ayurveda likely has a lot to offer as a FOUNDATION to start doing investigative research; but this claim of "any vedic sciences are arguably as rigorous as today's sciences" is bunkum. Show me any statistics / clinical trial data (or its equivalent) in the vedas?

I will accept & agree with the idea / contention that a lot of the treatments in ayurveda are possibly based on strong observations & correlations. Which is a good place to start modern scientific research from.

But to claim that ayurveda as written in, for instance, the Atharva Veda, is rigorous science demonstrates to me, a rather stark, depressing & baffling ignorance of modern science.

Last paragraph:

The University of California, Los Angeles, owns a U.S. patent (6,274,119) entitled “Methods for Labeling ß-Amyloid Plaques and Neurofibrillary Tangles”, which has been licensed to TauMark, LLC. Drs. Small, Satyamurthy, Huang, and Barrio are among the inventors and have financial interest in TauMark, LLC. Dr. Small also reports having served as an advisor to and/or having received lecture fees from Allergan, Argentum, Axovant, Cogniciti, Forum Pharmaceuticals, Herbalife, Janssen, Lundbeck, Lilly, Novartis, Otsuka, and Pfizer. Dr. Heber reports receiving consulting fees from Herbalife, and the McCormick Science Institute. The manufacturer of Theracurmin, Theravalues Corporation, provided the Theracurmin and placebo for the trial, funds for laboratory testing of blood curcumin levels, and funds for Dr. Small's travel to the 2017 Alzheimer's Association International Conference for presentation of the findings.

This is becoming an increasingly worrying trend - to bunk any analysis with a comment on 'small sample size, biases' that somehow moves to the top of the comment pile.

Statistically, there is no such thing as a 'small sample size', in isolation. It is always related to the power and effect that the researchers want to work with.

Moreover, even if a study is statistically insignificant, it DOES NOT mean that the opposite conclusion is true. It might often merit some further examination of cultural and historical trends. In this case, for instance, turmeric has been used for medicinal properties in Asian cultures for centuries. Theories of evolution suggest that this wouldn't be the case (and it would've died a natural death), if there wasn't some merit.

It is clear that you have not even read the Vedas to understand its implications on the world, especially in science. Most of the statistics that you ask have been lost due to them being so old, or deliberately destroyed. But we have the results to prove that these existed. "Strong observations & correlations" are just another way of saying "trial & errors".

Not just ayurveda, but take any science or even Mathematics. The Vedic civilization has been too far ahead of its European counterparts. In fact the idea of heliocentrism, gravity, action=reaction, universe & its age, speed of light, distance of the sun & moon from earth, understanding of time travel, time zones, metallurgy, the so called pythagoras theorem, sudoku & its various forms, the numeral system etc etc all have Indian/Vedic origins, so why would you doubt vedic medical sciences so much? There is also substantial evidence for surgery to have developed in Vedic India far earlier than Hippocrates or any Western counterpart. I firmly believe that if not for the muslim hordes who destroyed everything under the pretext of war, mankind would have been able to make better use of mankind's ancestral knowledge.
