Androstephium coeruleum is a small blue spring wildflower from the south-central United States. It is usually called blue funnel-lily. It is not a commercial herb, and you will not find it in shops.
The plant grows from a corm. A corm is a small round storage bulb that sits underground.
Grass-like leaves and a cluster of pale blue, funnel-shaped flowers appear in early spring. It is found in Texas, Oklahoma, Kansas, New Mexico and nearby states.
Here is the plain verdict. There are no human trials on this plant for any health use. Its chemistry has barely been studied.
It appears on broad lists of North American medicinal plants, but a listing is not a finding.
One point applies to this whole page. Long or wide traditional use is not proof that something works, and it is not proof that something is safe. For this species, even the traditional record is thin.
No mechanism is known for this plant, because no one has tested one.
There are no published cell studies, animal studies or human studies on blue funnel-lily extracts. Nothing is known about how it acts on nerves, gut, blood sugar or inflammation. Any claim that names a target is invented, not measured.
What can be said is general family chemistry. Blue funnel-lily sits in the asparagus family. Many plants in that family carry steroidal saponins, which are soapy plant compounds.
In laboratory work on other species, saponins can irritate the gut lining and break down red blood cells.
That is a statement about relatives, not about this plant. Nobody has shown that blue funnel-lily contains them, or in what amount. Treat the whole mechanism question as open.
This plant is not sold as a medicine in any normal market.
You may meet it in these ways:
- Seeds or corms sold for native-plant and prairie gardening. - The raw corm, dug by foragers in spring.
- A dried herbarium or teaching specimen. - Rarely, a home-made water infusion made by a forager.
There are no capsules, tinctures, standardised extracts or branded products. No maker tests it for purity, strength or contamination.
The plant appears in general reference lists of North American medicinal plants. Those lists are broad and are often not sourced to a named people or a named use.
Several Indigenous peoples of the Plains and Southwest dug the corms of spring bulb plants for food. That record covers a group of look-alike plants, including Triteleia and Brodiaea species. Blue funnel-lily is sometimes swept in with them.
A clear, well documented medicinal use for this exact species is hard to find. Where tradition is this thin, it should not be rewritten as a health claim. This page does not suggest trying it at home.
Stop at once and get medical help if you feel unwell after eating a wild bulb.
Call emergency services, or go to an emergency department, if you have any of these:
- Repeated vomiting that will not settle. - A slow heartbeat (bradycardia), or a fast heartbeat (tachycardia). - Faintness, or low blood pressure (hypotension) with dizziness on standing. - Numb or tingling lips, mouth or tongue. - Confusion, blurred vision or trouble breathing.
Take a sample or photo of the plant with you. It helps the team identify what you ate.
In the United States it is not an approved drug and is not marketed as a dietary supplement. No regulator has reviewed it for safety or effect. Digging wild plants on public land or protected ground may be restricted by state or federal rules.
