Andrographis: What it helps with, how to use it, and safety tips

Heard about andrographis for colds and wondered if it actually works? This short guide explains what andrographis is, when people use it, typical doses, and the safety points you need to know before trying it.

Andrographis (Andrographis paniculata) is an herb used in traditional medicine across Asia. Today, people take it mainly for upper respiratory infections, sore throat, and general immune support. Clinical reviews, including a 2017 meta-analysis of randomized trials, found andrographis can reduce symptom severity and shorten the length of common cold symptoms when taken early. That doesn’t mean it cures infections, but it can ease things and help you recover faster.

How people use andrographis

Most clinical studies use standardized extracts rather than raw leaf teas. Typical regimens seen in trials are extract doses in the range of 200–400 mg taken two to three times a day for 3–7 days during an acute cold. Look for products that state the andrographolide content (the active compound). If a product is standardized to andrographolide, it’s easier to compare doses. Always follow the label and check with your healthcare provider before starting.

Safety, side effects, and interactions

Side effects are usually mild: stomach upset, loss of appetite, or headache. Allergic reactions are possible but rare. Don’t use andrographis if you are pregnant — there is concern it could affect the uterus. Avoid it while breastfeeding unless your provider says it’s OK.

Andrographis can interact with some medicines. It may increase bleeding risk with anticoagulant or antiplatelet drugs, and it could affect immune-suppressing medications by changing immune activity. If you take diabetes or blood-pressure drugs, watch for unexpected changes and check with your doctor. Also consider stopping andrographis at least 1–2 weeks before scheduled surgery because of bleeding risk.

Quality matters. Buy from brands that use standardized extracts and have third-party testing for purity and heavy metals. Avoid products with vague ingredient lists or questionable claims. A good label will state the andrographolide percentage, batch number, and expiration date.

Thinking of trying it? If you take prescription meds, are pregnant, or have an autoimmune condition, talk to your clinician first. Use short courses for acute colds rather than long-term daily use unless under medical advice.
