Aristolochia rotunda - L.

Common Name Snakeroot
Family Aristolochiaceae
USDA hardiness Coming soon
Known Hazards The plant is poisonous in large quantities[7]. The plant contains aristolochic acid, this has received rather mixed reports on its toxicity. According to one report aristolochic acid stimulates white blood cell activity and speeds the healing of wounds, but is also carcinogenic and damaging to the kidneys[254]. Another report says that it is an active antitumour agent but is too toxic for clinical use[218]. Another report says that aristolochic acid has anti-cancer properties and can be used in conjunction with chemotherapy and radiotherapy and that it also increases the cellular immunity and phagocytosis function of the phagocytic cells[176].
Habitats Found amongst shrubs and herbaceous plants[45] along the sides of roads, in fields and in meadows[7].
Range Europe - Mediterranean. Occasionally naturalized in Britain[17].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Abortifacient  Antitussive  Diuretic  Eczema  Emmenagogue  Pectoral  Vermifuge  Vulnerary


The root is antitussive, diuretic, emmenagogue, pectoral, vermifuge and vulnerary[4, 7, 46, 61]. This herb should only be used internally with expert advice since large doses can provoke abortions as well as poisoning with inflammation of the mucous membranes, resulting in respiratory paralysis[7]. The plant contains aristolochic acid which, whilst stimulating white blood cell activity and speeding the healing of wounds, is also carcinogenic and damaging to the kidneys[254]. Externally the plant is used to treat a variety of skin complaints including eczema and difficult to heal ulcers[7]. The root is harvested in late spring and dried for later use[7].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Propagation

Seed - best sown in a greenhouse as soon as it is ripe in the autumn. Pre-soak stored seed for 48 hours in hand-hot water and surface sow in a greenhouse[134]. Germination usually takes place within 1 - 3 months at 20°c[134]. Stored seed germinates better if it is given 3 months cold stratification at 5°c[200]. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant out in late spring or early summer after the last expected frosts. Division in autumn[200]. Root cuttings in winter[200].
