**Citral**
Citral, a fascinating compound with a name derived from the Latin #0excludeGlossary has long been cherished for its vibrant #1excludeGlossary aroma. This naturally occurring terpene is found in the essential oils of various plants, including lemongrass and lemon myrtle. In the cannabis world, citral has carved out a niche for itself, thanks to its distinctive scent and potential health benefits. Historically, citral was primarily recognized for its role in perfumery and flavoring, but as the cannabis industry has evolved, so too has the appreciation for this aromatic compound. Today, citral is celebrated not only for its olfactory appeal but also for its potential to enhance the therapeutic effects of cannabis, offering #2excludeGlossary and antimicrobial properties. As cannabis enthusiasts seek out strains with unique and enticing aromas, citral continues to be a key player, adding a refreshing twist to the cannabis experience.

Citral is an acyclic monoterpene aldehyde. Being a monoterpene, it is made of two isoprene units. Citral is a collective term which covers two geometric isomers that have their own separate names; the E-isomer is named geranial (trans-citral; α-citral) or citral A. The Z-isomer is named neral (cis-citral; β-citral) or citral B. These stereoisomers occur as a mixture, often not in equal proportions; e.g. in essential oil of Australian ginger, the neral to geranial ratio is 0.61.
