Andrographis (Andrographis paniculata)

Echinacea (Echinacea spp.)

About

Andrographis, commonly known as Green Chiretta or King of Bitters, is an upright annual herb reaching approximately 3 feet in height. Native to India and cultivated throughout northern regions of India and China, this bitter medicinal plant has been valued in Ayurvedic and traditional Chinese medicine for centuries. MSK notes that it has been studied mostly for colds, flu and upper respiratory infections. The plant thrives on plains and in forest undergrowth, where its spotted pale brown or purple flowers and long seed capsules distinguish it from other medicinal herbs.

Echinacea (especially E. angustifolia and E. purpurea) is a perennial promoted today for colds on the idea that it may stimulate the immune system; NCCIH says taking echinacea may slightly reduce the chance of catching a cold, but it is still unclear whether it shortens a cold. Native Americans used echinacea for respiratory tract infections, tooth pain and snakebite; NCCIH says it is unclear whether echinacea helps other health conditions, including eczema.

Safety & precautions

Pregnancy & Breastfeeding: Avoid, because andrographis may affect fertility and uterine contractions. High doses can cause nausea, vomiting, and gastrointestinal upset. Medicines: MSK notes laboratory signs of reduced platelet clumping (although a rat study found no interaction with warfarin), possible added blood-pressure lowering, possible interference with some chemotherapy drugs, and a possible rise in side effects from aminophylline. Whether andrographis meaningfully blocks drug-processing enzymes is uncertain: MSK cites laboratory inhibition of CYP1A2, CYP2C9 and CYP3A4, while a 2015 review judged the data too limited to call it an inhibitor. Professional supervision is recommended for long-term use.

Allergy & Side Effects: NCCIH says echinacea is likely safe for most adults for short periods, but allergic reactions, which may be severe, can occur, and digestive upset is the most common side effect. It may also cause tingling in the throat. Autoimmune Disorders: Use with caution; strong immune stimulation might exacerbate certain autoimmune conditions. Mouth Sensation: Extracts often produce a scratchy sensation in the mouth or excess salivation.
