Seseli praecox · Accepted scientific name
Scientific literature: Very Sparse (1 studies) · ★☆☆☆☆
Seseli praecox is a distinctive perennial plant that belongs to the Apiaceae family. While it offers unique botanical interest, it carries specific chemical properties that require caution during handling. The plant contains falcarinol, a bioactive compound that can trigger adverse physiological reactions. This chemical makes the species a known skin-irritant, potentially causing discomfort upon contact. Therefore, individuals should exercise care and wear protective gear when interacting with this plant.

Identification
Biological Activities
Seseli praecox is an endemic Sardinian plant that serves as a notable source of the polyyne falcarinol. This specific compound has been identified as a potent skin irritant capable of inducing pro-allergic effects. Research indicates that falcarinol acts as a covalent CB1 receptor antagonist, which plays a significant role in its biological impact. By targeting keratinocytes, the substance increases the expression of pro-allergic chemokines like IL-8 and CCL2/MCP-1. Ultimately, these interactions suggest that the plant's chemical constituents can aggravate skin reactions and contribute to dermatitis.
Compounds
Seseli praecox is an endemic Sardinian plant that serves as a natural source of the polyyne falcarinol. This specific compound has been identified as a covalent cannabinoid CB1 receptor antagonist through recent isolation efforts. Once active in the body, falcarinol can induce pro-allergic effects by selectively alkylating the anandamide binding site within human CB1 receptors. Research indicates that this interaction increases the expression of pro-allergic chemokines in keratinocytes, which may lead to dermatitis. Consequently, the presence of falcarinol in Seseli praecox highlights the significant role of cannabinoid receptors in skin immunopharmacology.
