Lemon bedsheets are simple, lanceolate, with numerous milky white flowers arranged in panicles, forming a lucky charm design. This tropical shrub has small fruits akin to straying from pepper berries. This is also why it is nicknamed “mountain pepper”. Litsea citrata , also known as exotic verbena , is widely used in perfumes as an important component in cologne formulations. Native to Yunnan, China, it is actually found in tropical regions. Its fleshy fruit will give the essential oil a pleasant lemony scent .
Lemon Litsea essential oil is anti-inflammatory by inhibiting gamma interferon and IL-4 production. Also bronchial anti-inflammatory , it can be used in asthma by inhibiting cytokines as well as the production of reactive oxygen species, by inactivating the migration of eosinophils.
Antibacterial against Escherichia coli , the bed is also anti-infectious against anaerobic germs. Its activity antimicrobial and antibiofilm vis-à-vis Staphylococcus aureus , make citral it contains antiviral no less effective vis-à-vis the herpes virus I and II, influenza A H9N2 and the virus yellow fever.
Active on Helicobacter pylori , it is also antifungal against Candida albicans .
The anticancer properties of beds are due in particular to citral (lung, liver, oral cavity). This essential oil also induces apoptosis in lung cancer, even by dry inhalation.
Preventive of skin cancer, it notably reduces the chemo-induction of hepatocellular carcinomas (inhibition of FPTase activity and inhibition of P21ras expression). The D-limonene it contains indeed exhibits anticancer properties such that it is qualified as an emerging antineoplastic agent. Limonene would thus induce apoptosis via mitochondrial death and the suppression of cellular mediators.
Its potential action in chemoprevention as well as cancer chemotherapy, make it a detoxifying oil against carcinogens by induction of phase I and phase II enzymes. It inhibits, among other things, tumor promotion and progression by action on the p21ras proteins by tissue redifferentiation activity.
