What it is

Black seed (Nigella sativa) is an annual flowering plant native to South and Southwest Asia. Its seeds contain thymoquinone, a potent anti-inflammatory and antioxidant compound. In traditional Islamic medicine (Tibb-e-Nabawi) and Ayurveda, black seed is used postpartum for lactation support, uterine involution, and immune recovery.

How it works

Thymoquinone modulates NF-κB and NLRP3 inflammasome pathways, reducing postpartum inflammatory cytokines. Black seed has traditional galactagogue properties (milk-increasing) documented in Middle Eastern and South Asian ethnobotanical literature. It also supports uterine contraction and involution after delivery. Pregnancy use is controversial—most sources recommend postpartum-only use.

Who should take it

Postpartum women seeking traditional lactation support, immune recovery, and anti-inflammatory benefits after childbirth. Particularly relevant in South Asian and Middle Eastern cultural contexts where black seed is a traditional postpartum food.

Avoid / careful

NOT RECOMMENDED DURING PREGNANCY—may have uterine stimulant effects. Use only postpartum and during lactation. Those on anticoagulants should use caution (thymoquinone has mild antiplatelet effects). Discontinue before any surgery.
