Every immune & antimicrobial herbs entry in the Typed supplements library. Each one is a full page: what it does, stage by stage, and what the evidence says.
- AndrographisA very bitter traditional herb that may shorten a cold — but won’t stop you catching one.
- AstragalusA traditional Chinese root studied for immune support — the evidence so far is weak.
- Bee PropolisThe resin bees use to seal and protect their hive, taken as a supplement for immune support.
- Black Seed OilA cooking-oil seed studied mostly for blood sugar and blood pressure.
- Cat’s ClawA rainforest vine used traditionally to calm inflammation — with real but small evidence for one specific use.
- Chaga MushroomA hard, charcoal-like fungus that grows on birch trees, brewed as tea for centuries in Siberia — with lab-proven antioxidant activity but also a real, documented kidney-stone risk.
- Cranberry ExtractA tart red berry with real, Cochrane-reviewed evidence for preventing recurrent UTIs — as long as the product actually contains enough of its active compound.
- D-MannoseA natural sugar taken to try to flush UTI-causing bacteria out of the bladder — a good idea on paper, but the biggest trial so far found it didn’t beat a placebo.
- EchinaceaA prairie flower long used by Native American tribes and now a popular cold remedy — though the science on whether it actually helps is mixed.
- ElderberryA popular cold-season extract with real but modest evidence.
- GoldensealA woodland root long used in folk medicine for infections, now more notable for its drug interactions than proven benefits.
- Maitake MushroomA frilly, edible "dancing mushroom" studied for possibly softening post-meal blood sugar spikes and supporting immune activity — though the human evidence is thin.
- Olive Leaf ExtractA concentrated extract of the compound also found in olive oil — with a small, real effect on blood pressure.
- Oregano OilA strong-smelling plant oil that kills germs in a lab dish — but that hasn’t been shown to work the same way inside you.
- Pau D’ArcoA bitter bark tea from South America, traditionally called lapacho or taheebo, used for centuries in folk medicine.
- Stinging Nettle LeafThe same plant that stings your skin outdoors, dried and used as a supplement for allergy and joint pain relief.
- Turkey Tail MushroomA colourful bracket fungus whose extracted polysaccharide (PSK) is an approved cancer-adjunct drug in Japan — though the supplement you buy isn’t that pharmaceutical-grade product.
