From tradition to measurable biomarkers.
The research on Nigella sativa and immune function has moved from tradition to measurable biomarkers — T-cell populations, immunoglobulins, inflammatory markers — in controlled human trials.
A 2023 randomized, double-blind, placebo-controlled trial (n=52)
Healthy young adults studied Nigella sativa at 0.5g, 1g, and 2g per day over four weeks. At the 1g/day dose, total lymphocytes rose from 1,850 ± 0.24 × 10³/μL to 2,170 ± 0.26 × 10³/μL (p=0.008). CD3+ T-lymphocytes moved from 1,184 to 1,424 cells/μL (p=0.009). CD4+ T-helper cells moved from 665 to 841 cells/μL (p=0.002). No adverse effects at any dose.

Synthesized the inflammation data. Nigella sativa supplementation was associated with significantly reduced C-reactive protein (CRP; SMD = −2.28; 95% CI −3.20 to −1.37; p<0.001), TNF-α (SMD = −1.21; p=0.013), and MDA (SMD = −2.15; p<0.001), and with significantly higher total antioxidant capacity.
Inflammopharmacology, 2023 · PMID 37036558 →habb is not a stimulant for your immune system. It supports normal T-cell activity and a healthy, balanced inflammatory response — the upstream conditions a healthy immune system runs on.
Why one ingredient, not twelve
The active compound is what every study measures.
We show its number on the card. The number on your bottle should be the real one.
Every habb batch publishes three data points on the batch card:
Lab-verified by Eurofins / NSF / SGS. We use the conservative test, not the inflated one. The card shows the method.
Linoleic 57–61%, oleic 20–21%, palmitic 12–13%. If a supplement won't show you what's in the bottle, that's the answer.
For oxidation and contamination safety.
Sourcing: Ethiopian seeds, cold-pressed in California, one ingredient. The full how-it's-made math lives on the transparency page.
Cold-pressed in California from single-origin Ethiopian seeds.
How to use
One teaspoon, every morning.
The ceramic spoon ships with every bottle and holds the exact daily serving.
Take it straight, in warm water with honey, or stirred into a morning drink. The 1g/day dose in the T-cell trial is roughly one teaspoon of cold-pressed oil. Consistency — every morning, same time — is how the biomarkers in those trials moved.
