Caution: Excessive Use of Lemongrass May Be Harmful to Your Health

Excessive use of lemongrass may be harmful to your health.

Lemongrass, scientifically known as Cymbopogon citratus, is a common herb used in cooking to enrich food flavor. Many people are aware that this apparently common grass has many health benefits, too. Because of the many health benefits of lemongrass, many forms of preparations are sold in the lucrative alternative medicine market.

Health Benefits of Lemongrass

There are many health benefits of lemongrass which have been discussed extensively elsewhere. Among those alleged important health benefits of lemongrass are listed below:

Confounding Research Findings on Lemongrass

A very important and groundbreaking discovery that stands out among the health benefits of lemongrass listed above is that an essential oil extracted from the herb can cure cancer. A study conducted by Dudai et al. (2005) of the Hazeva Research and Development Center, Jacob Blaustein Institute for Desert Research, Ben Gurion University of the Negev, Beer Sheva, Israel revealed that lemongrass caused apoptosis or programmed cell death in cancer cells. This is due to the presence of citral in the herb. What is amazing is that a high concentration of citral induced apoptosis without harming the normal cells.

However, it is worthy to note that an earlier research found out that citral, the active component of lemongrass, can have the opposite effect to body cells. The findings of Geldoff and Rao in 1992 strongly suggested that citral can induce prostatic hyperplasia in rats. Simply stated, this refers to the enlargement of the prostate due to the estrogenic action of citral. Cells may abnormally increase in number due to citral. Citral can induce benign tumor that may eventually lead to cancer.

Disclaimer: No Approved Therapeutic Claims

While so many health benefits of lemongrass have been listed and touted by many advertisers and marketers, many of those health benefits are mainly speculation or not yet confirmed by science. The alleged health benefits of lemongrass are founded on anecdotal evidence. Anecdotal evidence means that the purported health benefits of lemongrass were based mainly on people’s testimonies which could not be construed as factual because these are just perceptions. Also, taking the herb's extracts would be beneficial for some people but these may not work for others.

This is the reason why many of health products have labels written on them: "No Approved Therapeutic Claims." This is a disclaimer that the producer of the product could not guarantee its efficacy. This may be because there were no studies or long-term research yet to determine the efficacy of the product in actually treating anything.

Conclusion

There is, therefore, a need to be cautious about herbal remedies or supplements because the desired effect may be contrary to what was expected. Again, the rule is to do things in moderation. Excessive use of products from the apparently harmless herb like lemongrass may in the long term be harmful to one's health.

Cautions that are good to know, thanks for sharing.

Very well written, Patrick. Anything too much in life is by itself disastrous. As for me I could just get rid of the grass and save the lemon. But certainly of course, when it comes to Filipino cuisine, lemongrass use is worth the risk to enjoy native delicacies at their best.

Good information. I like lemongrass, but now have to careful. Thanks.

Excellent write Patrick! Very fasianting subject and while it has numerous benefits as the saying goes all good things must come to an end. I am fasianted how it both can fight cancer and how it can create it at the same time, very unusual traits for a plant. I think more study has to be put into it. Terrific read. voted and tweeted!

Job well done on this alternative health plant.

Moderation is a key factor here. When one exceeds the limit, there's always a health hazard.

I have used it before, don't really like it much. Great article and I never thought you could over do it but I guess you can with most things!
