Catnip (Nepeta cataria)

Passionflower (Passiflora incarnata)

About

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. Catnip has an excitatory effect on cats.

Passionflower (Passiflora incarnata and related species) is a climbing vine that can grow up to about 30 ft (9 m). It features ornate, complex flowers - often white, purple, or blue - and lobed leaves. Traditionally used as a sedative, passionflower is taken for anxiety and sleep problems; NCCIH says a small amount of research suggests it might help anxiety and total sleep time, but conclusions are not definite. Some species, such as P. quadrangularis, contain serotonin-like compounds.

Safety & precautions

Large doses can cause vomiting. Ask a qualified professional before giving it to children or babies. Avoid during pregnancy.

Pregnancy: NCCIH says passionflower should not be used during pregnancy because it may induce uterine contractions. Drowsiness: May cause sedation; exercise caution with driving or machinery if taking a strong dose. Medication Interactions: Consult a healthcare professional if taking other sedatives or anti-anxiety drugs.
