Herb: Red Buckeye

Latin name: Aesculus pavia

Family: Hippocastanaceae (Horse-chestnut Family)

Medicinal use of Red Buckeye:

The powdered bark is hypnotic and odontalgic. It is used in the treatment of ulcers. A poultice of the powdered seeds has been used in the treatment of cancer tumours and infections, and as a salve for sores. An infusion of the roots has been used as a bath in the treatment of dyspepsia.

Description of the plant:


5 m
(16 feet)


Habitat of the herb:

Rich moist soils in deciduous woods, on the sides of streams and swamp margins.

Edible parts of Red Buckeye:

Seed - cooked. It can be dried and ground into a powder and used as a gruel. The seed is quite large, about 25mm in diameter, and is easily harvested. Unfortunately, the seed is also rich in saponins and these need to be removed before it can be eaten. See also the notes above on toxicity. The following notes apply to A. californica, but are probably also relevant here:- The seed needs to be leached of toxins before it becomes safe to eat - the Indians would do this by slow-roasting the nuts (which would have rendered the saponins harmless) and then cutting them into thin slices, putting them into a cloth bag and rinsing them in a stream for 2 - 5 days. Most of the minerals etc would also have been leached out by this treatment.

Other uses of the herb:

Saponins in the seed and roots are a soap substitute. The saponins can be easily obtained by chopping the seed into small pieces and infusing them in hot water. This water can then be used for washing the body, clothes etc. Its main drawback is a lingering odour of horse chestnuts.

Propagation of Red Buckeye:

Seed - best sown outdoors or in a cold frame as soon as it is ripe. The seed germinates almost immediately and must be given protection from severe weather. The seed has a very limited viability and must not be allowed to dry out. Stored seed should be soaked for 24 hours prior to sowing and even after this may still not be viable. It is best to sow the seed with its "scar" downwards. If sowing the seed in a cold frame, pot up the seedlings in early spring and plant them out into their permanent positions in the summer. Division of suckers in the dormant season. The suckers can be planted out straight into their permanent positions if required.

Cultivation of the herb:

Rich moist soils in deciduous woods, on the sides of streams and swamp margins.

Known hazards of Aesculus pavia:

The seed is rich in saponins. Although poisonous, saponins are poorly absorbed by the human body and so most pass through without harm. Saponins are quite bitter and can be found in many common foods such as some beans. They can be removed by carefully leaching the seed or flour in running water. Thorough cooking, and perhaps changing the cooking water once, will also normally remove most of them. However, it is not advisable to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish.
