Catnip (Nepeta cataria)

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. Historically used primarily for liver support and treating infections - especially malaria - it has earned recognition for its powerful immune-boosting and protective properties. 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.

Catnip is a downy, aromatic perennial growing to 3 feet with heart-shaped, gray-green leaves and whorls of white flowers marked with purple spots. Native to Europe and naturalized in North America, it grows in dry wayside places and mountainous regions up to altitudes of 5,000 feet. The plant is gathered when in flower during summer and autumn. Its name comes from the Norse word 'dylla,' meaning 'to soothe,' reflecting its calming properties. Catnip has an excitatory effect on cats but a sedative effect on humans.

Safety & precautions

Do not use during pregnancy or while breastfeeding, as andrographis may have effects on fertility and uterine contractions. High doses can cause nausea, vomiting, and gastrointestinal upset. Use caution if taking antiplatelet drugs or anticoagulants like warfarin, as andrographis may have additive antiplatelet effects and could modestly increase warfarin exposure, potentially raising bleeding risk. Monitor blood glucose closely if taking antidiabetic medications, since andrographis may lower blood sugar levels. Similarly, those on antihypertensive drugs should be aware of possible additive blood pressure-lowering effects. Evidence suggests andrographis might induce certain cytochrome P450 enzymes and moderately inhibit P-glycoprotein, though clinical significance remains unclear. Extremely large doses are discouraged and professional supervision is recommended for long-term use.

Generally mild and extremely safe, making it excellent for children and babies. However, extremely large doses can cause vomiting. Avoid during pregnancy. No other significant warnings for normal use.
