Nome comune: erba perla minore, erba perla bianca
Specie: Buglossoides arvensis (L.) I.M. Johnst. [Lithospermum arvense L.]
Famiglia: BORAGINACEAE
È una pianta annuale, alta fino a 50 cm, molto ramosa. Il termine generico richiama la somiglianza delle foglie alla lingua dei bovini (per la ruvidezza al tatto). Fiorisce dall’inverno sino agli inizi dell’estate.
- I fiori sono piccoli di colore bianco, bianco-giallastro, raramente purpureo, con corolla che di solito non supera i 5 mm, e asse fiorale allungato.
- Le foglie, frequentemente ruvide al tatto, sono generalmente erette e aderenti ai fusti, di forma lineare-spatolata.
- I fusti sono ramosi in alto, ruvidi al tatto per la presenza di fitti peli da ricurvi a eretto-appressati.
Si tratta di una specie officinale; in passato le foglie erano utilizzate in infuso come diuretico.

Buglossoides arvensis (L.) I.M.Johnst. |
Lithospermum arvense (syn. Buglossoides arvensis), known as field gromwell, corn gromwell, bastard alkanet, stone seed and Ahiflower®, is a flowering plant of the family Boraginaceae. It is native to Europe and Asia, as far north as Korea, Japan and Russia, and as far south as Afghanistan and northern Pakistan.[1] It is known in other places as an introduced species, including much of North America and Australia.[2],[3] The European Union has granted the refined oil of the seed of Buglossoides arvensis novel food status and some farmers are growing it[4]commercially in the United Kingdom as a plant-variety patented (PVP) and trademarked cultivar (Ahiflower). The seed oil contains high levels (63-72%) of omega-3 ALA (c18:3), omega-3 SDA (c18:4), and omega-6 GLA (c18:3)[5] and has GRAS (generally regarded as safe) review status from the US Food and Drug Administration, Canadian ingredient master file (IMF) registration and novel food status, and GMP+ Feed Support Product status in the EU for livestock and companion animals (including for defatted expeller press cake meal).
Refined Buglossoides oil has peer-reviewed published human clinical evidence from controlled dietary intervention trials showing up to 400% more efficient omega-3 EPA (c20:5) accrual in circulating cells vs flaxseed oil[6] and has been shown to significantly upregulate the cytokine interleukin-10 (IL-10) in lipopolysaccharide (LPS) stimulated macrophages by +40% vs. control[7]. IL-10 is recognized as one of the immune modulatory signaling cytokines that moderates the inflammatory response after intensive exercise or immune challenge.
Seeds of Buglossoides have been reported in Ukrainian archeological sites dating back as far as 4000 BC where they were stored in clay pots, however the purpose and usage of the seeds has not been determined. In modern European arable agriculture, Buglossoides often appears as a weed species with poor competitive and non-invasive characteristics.
