- Harvest
- Autumn (August-October) when the fruits are completely ripe and reddish
Seeds (stones) of the fruit of Ziziphus spinosa collected in autumn. The pulp is crushed, the bones are extracted, and they are shelled to obtain the flat ovoid seeds.
Clean seeds, shells removed, washed and dried in the sun. For decoction, they are crushed just before use to release the active ingredients (jujubosides, spinosin).
Dry fried seeds over medium heat until they are slightly swollen and have a toasted aroma. This is the most used form clinically.
