Back to school, back to the evidence

George County is back in the building, and the shop is already stocking the usual late-August basket: elderberry, echinacea, vitamin D, and a jar of local honey. Before anyone reaches for the phrase "immune boost," here is what the newest human studies actually say.

What the papers found

Echinacea has the cleanest 2024 prevention signal. A meta-analysis in Antibiotics pooled 30 trials (5,652 people) and linked echinacea with fewer monthly respiratory infections and fewer people who then needed antibiotics. Fresh Echinacea purpurea alcoholic extracts looked strongest. Side-effect rates matched control. NIH's NCCIH is more cautious: it may slightly lower the chance of catching a cold, and it is still unclear whether it shortens one. Products differ a lot by species, plant part, and extract. Daisy-family allergy is a real reason to skip it.

Elderberry is the fan favorite, and the evidence is thinner. The best human systematic review (Wieland et al., 2021, still the one NCCIH cites) found that elderberry did not clearly prevent colds. It may shorten and soften a cold or flu, but the certainty is low. Use cooked berry products only. Raw or unripe berry, leaf, and stem are toxic. No COVID claims.

Vitamin D needs an honest reset. A 2025 update in The Lancet Diabetes & Endocrinology (40 trials, 61,589 people) did not find a statistically significant drop in acute respiratory infections. That is not a reason to ignore a documented deficiency. It is a reason not to sell D3 as a back-to-school cold shield. The K2 in our D3+K2 formulas is there because D and K work on the same calcium-handling proteins, not because K2 has been proven to protect arteries. A 2022 Circulation trial of high-dose K2 plus D3 did not slow aortic-valve calcification. Anyone on warfarin or another vitamin-K antagonist should talk with the clinic first.

Honey is the quiet winner for kids' cough. A 2023 review in the European Journal of Pediatrics (and Cochrane before it) found low-quality but meaningful evidence that honey may cut cough frequency and help sleep a bit more than placebo or some OTC syrups. Never give honey to infants under 12 months (botulism). It is not a pneumonia or flu treatment.

Handwashing, sleep, and a clinic visit still come first.

Coming up next week

School-year stress and sleep: ashwagandha. A 2024 meta-analysis in Explore found lower perceived-stress and anxiety scores in adults, with a cortisol drop to match. Stronger story if we lead with safety: not in pregnancy, rare liver-injury reports, and a clinic check if you take thyroid, diabetes, or sedative medicines.
