Related to thorny locust: Honey locust tree, Gleditsia triacanthos
Tree grows up to 80 ft (27m) with thorns, greenish flower clusters, flat twisted fruit pods, which are antiseptic, anti-fungal, antibacterial. Pod tea used for lung, stomach and heart issues. Leaves contain anti-cancer compounds. Anything this powerful could be toxic if taken in high doses. There is a similar tree called the Black Locust (Robinia pseudoacacia) that is toxic and doesn’t have the long branched spines on the trunk, instead having pairs of short thorns at the base of each leaf; the leaflets are also much broader on the toxic version.
