Andrographis
Best-in-class: Andrographis
An immune herb with strong evidence for shortening colds and respiratory infections — sometimes called 'Indian echinacea.'
How Andrographis actually works
Andrographolide has anti-inflammatory activity through NF-kB inhibition, plus immunostimulant and antiviral effects in vitro. It is one of the more pharmacologically active herbs in this category rather than a gentle traditional remedy.
Andrographis quick facts
| Suggested dose | As directed at first symptoms (standardized andrographolides). |
| How often | Acute only - at the first symptom, short courses |
| Who it's for | Cold/flu and respiratory-infection support. |
✅ Clinically validated
- Meta-analyses support reduced severity and duration of upper-respiratory infections.
- Immune-modulating and anti-inflammatory activity.
📊 Correlative data
- Traditional cold/fever use aligns with the respiratory-infection trials.
🧪 Theoretical / extrapolated benefits
- Andrographolide inhibits NF-κB and has documented antiviral activity in vitro against several respiratory viruses. The prediction is a shortened and blunted upper respiratory infection rather than prevention of one — which matches where the trial signal actually sits.
- Predicted downside worth naming: the same immune modulation is theoretically the wrong direction in autoimmune disease, and there are case reports of anaphylaxis. Not a supplement to take continuously.
These tiers tell you how much human evidence exists — not how well something works. This is the research space, and most of what’s in here is new rather than disproven. Something sitting at “theoretical” usually means nobody has funded the trial, not that the trial was run and failed.
The trap runs the other way too: something can be clinically validated and still do very little for you specifically. A statistically significant result in a study population is not a promise about your body.
- ✅ Clinically validated — human randomised trials or meta-analyses support it. The strongest footing available.
- 📊 Correlative — observational or epidemiological data. Suggestive, and genuinely useful for direction, but it cannot establish cause.
- 🧪 Theoretical / mechanistic — the mechanism is understood and often demonstrated in cells or animals, and the human trial doesn’t exist yet. Unproven is not the same as ineffective. Plenty of what’s standard practice today sat here five years ago.
✗ is a safety flag, not a grade. Where you see it, the concern is harm — not a disappointing trial. A compound tested for one purpose and found not to help there can still be worth studying somewhere else, so a negative result never gets rendered as a cross. It sits alongside the tier, because something can be both well-studied and genuinely risky.
My job is to tell you which one you’re looking at, and let you make the call. Grading something low isn’t me dismissing it — it’s me refusing to oversell it. This is the research space, and being able to reason forward from a mechanism matters as much as waiting for the trial.
Meta-analysis supports symptom reduction in upper-respiratory infection, and it is one of the better-evidenced botanicals here. It is intensely bitter, which limits compliance in unencapsulated form. Real cautions: it may be abortifacient, has antiplatelet activity, and there are rare reports of anaphylaxis and liver injury. Not one for continuous long-term use.
Andrographis — safety & side effects
- GI upset, headache, fatigue and a very bitter taste that many people cannot tolerate.
- Immunostimulant — caution with autoimmune disease and with immunosuppressants, including after a transplant. Stimulating an immune system that is already attacking you is the wrong direction, and 'natural' does not change that.
- Antiplatelet activity and blood-pressure lowering — Additive bleeding risk with anticoagulants and antiplatelets — warfarin, apixaban, rivaroxaban, clopidogrel, and aspirin at any dose. The interaction is pharmacodynamic rather than metabolic, so it does not show up as a changed drug level; it shows up as bruising, nosebleeds or a raised INR.
- Avoid in pregnancy: animal data show antifertility and abortifacient effects. Rare reports of allergic reactions including anaphylaxis.
