The Re-Emerging Ancient Black Sea Crop

Historically cultivated across the Samsun and Kastamonu valleys of northern Anatolia for durable sailcloth and medicinal seeds, Hemp (Cannabis sativa, Cannabaceae; Turkish: Kenevir) produces an emerald-green seed oil with an extraordinary nutritional architecture.
  1. The Biological Golden 3:1 Ratio: Nutritionists recognize an ideal dietary ratio of $3:1$ linoleic acid (omega-6) to alpha-linolenic acid (omega-3). Hemp seed oil naturally hits this exact evolutionary target.
  2. Gamma-Linolenic Acid (GLA) & Stearidonic Acid (SDA): Hemp seed oil provides $2 - 4\%$ GLA and $1 - 2\%$ stearidonic acid, bypassing the rate-limiting delta-6-desaturase enzyme and fueling rapid synthesis of anti-inflammatory eicosanoids. In clinical dermatology trials (Callaway et al.), dietary hemp seed oil significantly reduced dryness, itching, and trans-epidermal water loss in subjects with atopic dermatitis.
