Aesculus turbinata

Blume

Sapindaceae


This species has been confused in China with Aesculus chinensis, but it differs in several characters, including its sessile (vs. petiolulate) leaflets, crenulate (vs. serrulate) leaflet margin, conic or cylindric-conic (vs. cylindric) thyrse, and verrucose (vs. dotted but smooth) capsule[

]. 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[

Cultivation Details

Aesculus turbinata is said to prefer a continental climate with its hot summers, cold winters and usually a clear movement from one season to another. The dormant plant is very cold tolerant, but in more maritime climates it is often tempted to come into growth early and this new growth can easily be damaged by late spring frosts[

]. The seed is quite large, about 25 - 30mm in diameter, and is easily harvested. Unfortunately it is also rich in saponins and these need to be removed before the seed can be eaten. See also the notes above on toxicity.
The following notes apply to Aesculus californica, but are probably also relevant here:-
The seed needs to be leached of toxins before it becomes safe to eat - the native North Americans 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[
