How this ranking works: we rank only products we've reviewed in full, using the same four criteria — formulation, ingredient transparency, value for money and guarantee. It's our editorial opinion, not a list of every product on the market, and placements are never paid. Our method.

Ten non-GMO medicinal herb seeds to grow a 'backyard pharmacy'. As a product, the Medicinal Garden Kit is refreshingly honest: you're buying quality seeds and guidance, not miracle claims.
A 57-ingredient greens powder with quercetin, mushrooms and probiotics. TonicGreens is a legitimately well-stocked greens powder — quercetin, resveratrol, curcumin, medicinal mushrooms, and probiotics make for a useful daily antioxidant and gut-support boost.
A 375-page food-therapy guide rooted in Traditional Chinese Medicine. Judged as an inexpensive food-therapy e-book, The Encyclopedia of Power Foods is a reasonable, if oversold, buy.
What to look for
- Food first — whole vegetables, herbs and fiber do most of the work; products should support that, not replace it.
- Polyphenol-rich ingredients — quercetin, curcumin, mushrooms and greens in a greens powder.
- Realistic claims — no product 'boosts' immunity overnight or cures disease.
- Effort required — a seed kit or e-book only pays off if you use it.
- Long guarantees — the seed kit's 365-day window is one of the longest we've seen.
