Product Abstract

Lemongrass is a tall perennial plant belongs to grass (Poaceae) family. Lemongrass essential oil is used as aromatherapy to relieve muscle pain and also known as mosquito, insect and ant repel.  Its clean and calming aroma helps relieve stress, anxiety, irritability and insomnia, and prevent drowsiness. It has high source of vitamins such as vitamin A, B1, B2, B3, B5, B6, folate and vitamin C. It also works as an air freshener and deodorizer, it can also be used for flavouring tea and soups, and it adds fragrance to cosmetics, soaps.


Lemongrass oil, used as a pesticide and preservative, is put on the ancient palm-leaf manuscripts found in India as a preservative. It is used at the Oriental Research Institute Mysore, the French Institute ofr Pondicherry, the Association for the Preservation of the Saint Thomas Christian Heritage in Kerala, and many other manuscript collections in India. The oil also injects natural fluidity into the brittle palm leaves, and the hydrophobic nature of the oil keeps the manuscripts dry so the text is not lost to decay due to humidity

Although considered safe, the topical use of lemongrass oil or the ingestion of herbal tea made of lemongrass can result in allergic reaction in some people. In the event of any allergic symptoms, it is always advisable to discontinue the use of lemongrass oil and seek immediate medical attention.

Undiluted or concentrated lemongrass oil should not be applied directly on the body as it may result in harmful reactions. It is always advisable to keep pure lemongrass oil out of the reach of children.

It is strongly recommended to consult a health professional before considering lemongrass oil for therapeutic usage; especially during pregnancy when trying to conceive, breastfeeding, and during the course of any ongoing medical treatments.

Safety summary
Hazards  Drug interaction; teratogenicity; skin sensitization.

Cautions (all routes)  Drugs metabolized by CYP2B6.

Cautions (oral)  Diabetes medication, pregnancy.

Cautions (dermal)  Hypersensitive, diseased or damaged skin, children under 2 years of  age.
Maximum daily oral dose in pregnancy  46 mg
Maximum dermal use level 0.7%

Our safety advice
We recommend a dermal maximum of 0.7% to avoid skin sensitization, and a daily oral maximum in pregnancy of 46 mg. This is based on 90% citral content, with dermal and oral citral limits of 0.6% and 0.6 mg/kg.

Regulatory guidelines
Has GRAS status. IFRA recommends a maximum dermal use level for citral of 0.6% for body oils and lotions, in order to avoid skin sensitization.

Organ-specific effects
Adverse skin reactions  Undiluted East or West Indian lemongrass oil was moderately irritating to rabbits, and was mildly irritating to mice and pigs; tested at 4% on 25 volunteers it was neither irritating nor sensitizing. It is non-phototoxic. Lemongrass oil  tested at 2%, induced allergic responses in 25 of 1,606 consecutive dermatitis patients. In  such patients, there were four reactions to 2% East Indian lemongrass oil. There were no irritant or allergic reactions to 1% lemongrass oil in a group of 100 such patients.

Cardiovascular effects  Gavage doses of 10, 15 or 20 mg/kg/ day citral for 28 days, dose-dependently lowered plasma insulin levels and increased glucose tolerance in obese rats.

Reproductive toxicity  Citral is dose-dependently teratogenic because it inhibits retinoic acid synthesis, and this can affect fetal development.

Systemic effects

Acute & subacute toxicity  East Indian lemongrass oil acute oral LD50 in rats 5.6 g/kg; acute dermal LD50 in rabbits >2 g/kg. West Indian lemongrass oil acute oral LD50 in rats >5 g/kg; acute dermal LD50 in rabbits >5 g/kg. When West Indian lemongrass oil was administered orally to mice for 21 days at 1, 10 or 100 mg/kg, therewere no significant changes in gross pathology, bodyweight, absolute or relative organ weights, histology, urinalysis or clinical biochemistry in the treated mice relative to the control groups.

Antioxidant/pro-oxidant activity  In both egg yolk and rat liver assays, West Indian lemongrass oil showed a strong pro-oxidant activity at all the concentrations tested.West Indian lemongrass oil scavenged DPPH radicals, with an IC50 of 27.0 mL/mL, compared with 31.4 mL/ mL for BHT. Lemongrass oil  significantly induced glutathione S-transferase activity in mouse tissues.

Carcinogenic/anticarcinogenic potential  When given to mice at 500 mg/kg for six weeks, West Indian lemongrass oil was antigenotoxic, mitigating leukocyte DNA damage induced byMNU. Doses of 100 mg/kg for 3 weeks had no such antigenotoxic effect, but were not genotoxic. East Indian lemongrass oil showed good in vitro cytotoxic activity against 12 human cancer cell lines, representing cancers of the cervix, lung, liver, colon, prostate, mouth and nerves, with IC50 values ranging from 4.2–79.0 mg/mL. Administration of the oil at 200 mg/kg ip in mice, inhibited Ehrlich and Sarcoma-180 tumors from 37–97%, primarily due to apoptosis.

Drug interactions  Antidiabetic medication, because of cardiovascular effects, above. Since citral and geraniol inhibit CYP2B6, there is a theoretical risk of interaction between lemongrass.

The validity of the quenching phenomenon is disputed, and sensitization reactions from lemongrass oil are certainly possible. Uter et all reported a good correlation between sensitivity to lemongrass and citral among 1,777 patients tested with both substances. Their data also show four times as many reactions to lemongrass oil in patients suspected of fragrance sensitivity as in consecutive dermatitis patients. There are insufficient data to determinemaximumdermal use levels, but for dermatitis patients this will be below1.0%, possibly in the region of 0.5%. Lemongrass oils are sometimes rectified to produce an oilwith up to 95%citral. A novel chemotype of C. citratus is now being cultivated in Uttarakhand, India, containing 40% geraniol, 24% citronellol, 7% geranial and 5% neral.
