Nigella sativa

Black seed (Nigella sativa) is documented in Anatolian-Islamic medicine for nearly fourteen centuries. The plant is grown in the central Anatolian plain — primarily Konya and Niğde — and forms one of the four anchor plants of the Thermées line.

In the hammam tradition, black seed oil was rubbed into the scalp and skin after the bath. Modern dermatology has confirmed several of the historical claims (acne reduction, mild antibacterial effect), but Bithyné does not lean on clinical language. The plant has earned its place over centuries of practice.

Properties: antibacterial, sebum-balancing, deeply nourishing. Traditional uses: scalp oil, post-bath skin, after-shave equivalent.
