We rely on donations from our users to keep maintaining and extending our free-to-use database of over 8000 edible and useful plants. Currently we are also investing time and effort in preparing two new books on plants suitable for food forests in different warmer climate conditions, to complement the one we published in 2021 on temperate food forests, which has been very well received. Please give what you can to help us complete this work. More >>>

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.

The seed contains small quantities of the hallucinogen LSD[200, 219]. This has been used medicinally in the treatment of various mental disorders.

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.

Cultivation details

Landscape Uses:Container, Specimen. Requires a rich well-drained soil in a warm sunny position[1]. A tender and short-lived perennial plant, it can survive the winter when grown against a sunny but sheltered south-facing wall though it is best treated as an annual[219]. A climbing plant, supporting itself by twining around the branches of other plants[219]. There are many named forms selected for their ornamental value[219]. Special Features: Attractive foliage, North American native.

Pre-soak the seed for 12 hours in warm water, or scarify the seed, and sow in individual pots in a greenhouse in early spring. The seed usually germinates in 1 - 3 weeks at 22°c. Plants are extremely resentful of root disturbance, even when they are quite small, and should be potted up almost as soon as they germinate[219]. Grow them on in the greenhouse for at least their first winter then plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of side shoots in a peaty soil. Layering.

I. tricolor doesn´t contain LSD. But what it does contain is the chemically and pharmocologically related entheogen ergine. Ergine is in fact "d-lysergic acid amide" (sometimes known as LSA), whereas LSD is "D-lysergic acid diethylamide" which has never been found to occur naturally in neither plants or animals. Recommended reading on the subject: "Pharmacotheon" by Jonathan Ott, or , "The Botany and Chemistry of Hallucinogens" by Richard Evan Schultes and Albert Hofmann.

Concerning medicinal uses: Morning Glory contains LSA (lyseramide), a chemical cousin of LSD. Although similar, the effects of LSA are reportedly less intense and slightly different.

there are six cultivars: heavenly blue (sometimes called clarke's early) summer skys (pale blue) wedding bells (lavender) blue star (pale blue with darker blue star) flying saucers (blue/white stripes and speckles) pearly gates (white)

After observing gray squirrels picking and eating morning glory leaves along my back yard fence, I tested them for safety. First I chewed a small amount then spat it out. Next day I chewed and swallowed a small amount. A few days later I picked sever leaves and added them to stir fry. Neither my wife nor I have ever had any negative reaction to eating morning glory leaves either fresh in a slad or cooked in stir fry.

Interesting, I found one other report of experimentation on the net but can't find anything else about the leaves being edible (or poisonous for that matter). There are a lot of things animals can eat we cant, although if there something they leave alone it's usually wise to follow suit! There are a lot of wild foods you can eat in moderate amounts but eaten in quantity they become toxic, some plant toxins can build up in the system over time (I don't know how common this is, I expect a doctor would) The scientific book 'Phytochemistry of Medicinal Plants' reports finding toxicity in the "aereal parts" (presumably the leaves), but this is an experiment with extracts in lab experiments against tumors, it may not be relevent). A few authorities say the hallucinogenic seeds can be fatal, most say harm is moderate, at least physically, this particular risk is definately not an issue with the leaves.
