Khurasani Ajwain, Black Henbane (Hyoscyamus niger)

Parasika Yavani (Hyoscyamus niger) is a 30-150 cm tall erect viscidly hairy annual herb with a nauseating odor. The plant comes in two varieties: annual and biennial. During the summer, the annual grows to a height of 30 to 60 cm (1 to 2 ft), then blossoms and sets seed. During the first season, a tuft of basal leaves appears, which disappears in the winter, and leaves underground a thick meaty root. Flowering and fruiting take place from April to September. The stem can grow to be many meters tall.

  • The leaves have irregularly shaped, smaller, sessile, oval lobes that are placed sporadically.
  • Bisexual, funnel-shaped flowers have a center of dark purple reticulation and a yellowish-green tint. The fruit has several black seeds enclosed in it.
  • The oval, kidney-shaped seeds have a dark grey hue, a diameter of around 1.5 mm, and a pungent, bitter, and mucilaginous flavor.

The plant produces a branched flowering stem the following spring that is typically significantly taller and more powerful than the annual plants' flowering stems.
