What the world's traditions say about herbs and the body — and what science says about it. No sugar-coating: confirmed, partial, and disputed claims, all shown honestly.

Human use for gastric ulcer disease is a long-documented traditional application, and a 2025 animal study found glycyrrhizin reduced toxin-induced damage and cell death in stomach tissue through anti-inflammatory pathways — but this evidence comes from a poultry model exposed to a specific mycotoxin, not from human ulcer trials.

Modern clinical research, including a 2022 Cochrane overview, concludes that pelvic floor muscle training is generally recommended as first-line therapy for stress, urgency, and mixed urinary incontinence in women, ahead of medication or surgery. Later work refined the picture further, showing that training type, dose, and supervision all affect how well it works.

The claim that pelvic floor dysfunction is a treatable, muscle-based condition rather than an unavoidable fate is well supported: research identifies pelvic health physical therapy as a recognized first-line treatment linked to improvements across a wide range of conditions. However, the same research shows a severe access gap, with only 1,135 certified pelvic health physical therapists counted across the entire United States as of mid-2022.

For people who already have intermediate or advanced AMD, large randomized trials show that an antioxidant-plus-zinc formula (including 500 mg vitamin C) slows disease progression and vision loss. This is a treatment-for-existing-disease claim, not a prevention claim, and it does not isolate vitamin C's individual contribution from the cocktail.

Although observational studies link higher dietary and blood vitamin C with lower cataract risk, a Cochrane review of nine randomized trials across 117,272 people found no evidence that supplementing with vitamin C, vitamin E, or beta-carotene actually prevents cataracts, reduces cataract surgery, or slows vision loss. This is a clear case where association did not hold up under rigorous randomized testing.

Trials in shift-working nurses and sleep-deprived physicians used validated fatigue and cognitive-performance measures and found benefits over placebo, and a formal systematic review found supportive evidence across the majority of physical-fatigue trials it examined. The evidence is consistent but still comes from a modest number of trials, so it counts as promising rather than definitive.

Modern research has begun testing whether these ancient constitutional categories map onto real biological variation. Genome expression and metabolomic studies found statistically distinct molecular profiles between people classified as Vata, Pitta, or Kapha types, with patterns aligning with classical predictions. A broader review found associations between Prakruti types and metabolic markers and disease risk, but the evidence base remains small and preliminary rather than fully validated.

A 2026 systematic review identifies weakened prefrontal-limbic connectivity and dopamine dysregulation as core problems in substance use disorders, and lists Mindfulness-Based Relapse Prevention among therapies studied alongside CBT and EMDR for these disorders. The review frames mindfulness as one option among several rather than a standalone fix, and calls for better biomarkers to match therapy to individual brain profiles.

Modern science doesn't recognize a direct anatomical channel between the sole of the foot and the eyes, so the traditional mechanism itself isn't validated. However, a small 2016 clinical trial testing the practical outcome found that adding sesame oil foot massage to a licorice supplement improved eye weakness in 70% of participants versus 33% with the supplement alone, a promising but preliminary result from a single small study.

Modern research confirms vitamin D deficiency is widespread globally and directly causes nutritional rickets in children and osteomalacia in adults by impairing calcium absorption and bone mineralization. Breastfed infants are a specific at-risk group requiring supplementation since breast milk is naturally low in vitamin D.

Modern research finds people with Hashimoto's thyroiditis and psoriasis have significantly lower vitamin D levels than healthy controls, and supplementation in deficient Hashimoto's patients has been shown to lower thyroid autoantibody titers, suggesting a genuine immune-modulating role. In psoriasis, hypovitaminosis D is considered a real risk factor, though evidence for oral supplementation reversing severity is less definitive.

Modern epigenetics broadly supports the idea that lifestyle and diet can switch genes on or off without altering the DNA sequence itself, and a 2020 paper argues this lines up conceptually with the Janma/Deha Prakruti distinction. It's an early, largely theoretical parallel rather than a proven mechanistic match.

Modern trials show the bone-building claim is real but conditional: benefit depends on baseline vitamin D/calcium deficiency, dose, and population studied, and vitamin D alone (without calcium) has not consistently shown fracture prevention. The effect on bone mineral density is measurable, but fracture-prevention evidence is much weaker and more mixed than the traditional 'calcium equals strong bones' assumption.

The old fear that calcium supplements cause kidney stones has largely not held up: a systematic review of decades of trial and observational data found most studies show no increased stone risk with high calcium intake, and many point toward an inverse relationship. One early Women's Health Initiative report did show a small increase, which likely fueled the enduring popular belief.
