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).
Safety Profile
While lemongrass is generally considered safe for most people, it is important to approach its use with caution. Lemongrass might alter the metabolism of medications that are cytochrome P450 substrates, potentially leading to enhanced or reduced drug effects (Li et al., 2018)
Like other essential oils, lemongrass essential oil may cause allergic reactions and/or sensitization, although these reactions are rare (Mills & Bone, 2013; Tisserand & Young, 2014). It is therefore important to perform a patch test before using products containing it for the first time. Apply a small amount of the product to a small tender area of skin such as the bend of the arm and leave for 24 hours. If you feel any irritation or reaction, wash with soap and water and do not use the product anymore.
As with any herbal remedy, it is prudent to consult with a healthcare professional before using lemongrass, particularly if you have a pre-existing medical condition, if you are pregnant or breastfeeding or if you are taking prescription medications.
