Cassia occidentalis: Faux Coffee & Greens

You either cook the Cassia Clan right or they make you sick. Any questions?

Cassia occidentalis

Now that I have your attention, they are not as bad as a lot of the toxic plants around, especially if you’re an adult. But, the raw seeds in 2007 did cause the death of three children. On the other side, some Cassias have been used as a coffee substitute and pot herbs since ancient times.

The young shoots, leaves and unripe pods of the Cassia occidentalis, C. marilandica and C. tora, are edible AFTER boiling in a change of water to reduce the strong smell. The torrified seeds are used as a coffee substitute, though nothing really substitutes for coffee.

Cassia seeds

That’s all fairly straight-forward until one adds that botanists just can’t leave a genus name be, so the Cassia are also known as Senna marilandia, S.occidentalis, and S. tora.

Cassia (KASS-ee-uh) comes from the Greek word Kassia (ka-SEE-ah.) It was a desert name for some unnamed plant. Marilandica (mary-LAND-ik-uh) means of Maryland, occidentalis  (ok-sid-en-tay-liss) of the western world, and tora (TORE-ah) what it means botanically I do not know… Tora is “lion” in Japanese, “now” in Greek.  Senna (SEN-uh) is an Arabic name for a thorny bush.

Cassias are found from about west Texas north to Iowa and Florida north to Massachusetts, with California sometimes tossed in.

Long time now to comment on the interesting topics of Eattheweeds favourable newsletter; indeed I have missed it so much. Now by chance it happened I am searching to identify a plant that has black glands which exudate sweet sugar – makes more interest – close of stem and raised on the leaf stalk . Luckily I have found the expertee. My plant grew wild and has the seeds exactly as described. I only wonder whether to use the seeds for trying making coffee substitute to use ripe and hard or before ripening !
