Black Cumin Seed Oil helps calm the nervous system, quells colic pain, stimulates urine production, helps treat pertussis, improves digestion and helps prevent and lower high blood pressure. The Seed Oil treats flatulence, diarrhea, haemorrhoids, constipation and dysentery. The Seed Oil is effective in curing abscesses and tumours of the eye, abdomen and liver, probably due in great part to the anti-tumour compound beta-sitosterol found in the seeds. The Black Cumin Seed Oil comes in HDPE carboys.
