Lemongrass (Cymbopogon citratus)

Overview and Health Benefits

Lemongrass (Cymbopogon citratus) is celebrated both in traditional medicine and modern herbalism for its wide range of therapeutic properties. This plant is utilised primarily for its essential oils, which are extracted from its leaves – but the leaves can also be integrated into teas or dishes. Empirical research and centuries of cultural healing practices support the use of lemongrass in promoting digestive health, relieving pain, and enhancing emotional wellbeing.

Key Benefits and Uses:

Digestive health: Lemongrass supports the digestive system, in particular by alleviating symptoms of indigestion, bloating, and constipation. Its antispasmodic properties soothe stomach cramps, and its carminative effect helps reduce flatulence (Shah et al., 2011; Hodges, 2015).

Pain relief: The analgesic properties of lemongrass can help reduce pain associated with headaches, muscle aches, and joint discomfort (including rheumatic and arthritis pain). The essential oil is often used in topical preparations for this purpose (Worwood, 1991; Skaria et al., 2007).

Antimicrobial activity: Lemongrass possesses potent antibacterial, antiamoebic, and antifungal properties, making it beneficial in the treatment of skin infections and as a supportive treatment in candidiasis (Onawunmi et al., 1984; Naik et al., 2010; Shah et al., 2011).

Emotional wellbeing: Lemongrass is traditionally used in aromatherapy for its ability to alleviate stress and anxiety and promote a sense of calm. However, although lemongrass tea is traditionally used to reduce anxiety in Brazil, when given in a double-blind clinical trial to volunteers, no differences could be made against placebo – indicating further studies are needed on dosage and extraction type (Leite et al., 1986). 

Antioxidant properties: High in antioxidants, lemongrass supports the body's defence mechanisms against oxidative stress, which is linked to many chronic diseases (Shah et al., 2011).
