“When life gives you lemons, make lemonade” is a famous proverbial phrase that tells us to look at the bright side and keep moving forward in life. Just like the saying, lemons or Citrus limon are bright yellow, oval-shaped edible fruits with a pronounced bulge on one end. Lemons are available in different sizes, with the raw ones being green in colour and the ripe ones turning a beautiful bright yellow. Lemons are native to the Himalayan foothills of Thailand, Indonesia, the Philippines and North India. In India, they are the third largest crop after bananas and mangoes and thus, they have become an economically important crop.
This flavoured fruit has a juicy yellow flesh that is sour in taste. Their tartness and citric fragrance make them a kitchen favourite. James Lind, the pioneer of clinical research, carried out the very first clinical trial in history with lemons as his focus. The findings of this trial supported the use of lemons for treating scurvy. Let’s find out more about this lovely fruit!1,2
Lemons are packed with the goodness of minerals and vitamins, especially Vitamin C and polyphenols like polymethoxyflavones. The nutritional components of lemons are mentioned in the table below.

Scientifically proven properties of C.limon include:
Some of the potential benefits of lemons are described below.
Plant constituents like polyphenols may help manage obesity. Fukuchi et al. conducted a study in 2008 to assess the effect of lemon polyphenols on obesity in white mice. Polyphenols in lemons might be responsible for suppressing fat accumulation and weight gain in the body. This indicates that the consumption of lemon may help in managing obesity. However, scientific evidence supporting this claim is limited, and this warrants the need for conducting further research.6
Cancer is the leading cause of death, and literature reviews have shown a clear positive relationship between dietary polyphenols (which are strong antioxidants) and cancer. Al-Ataby conducted a study in 2022 to assess the effect of lemon and ginger administration on breast cancer tumour growth in mouse models. The findings of this study support that 50% of mice consuming the lemon-ginger combination did not develop tumours due to the presence of alpha-pinene and alpha-terpineol. This indicates that the consumption of lemon may show anti-cancer properties. However, we need more studies to support these claims.7
Along with antihypertensive medications, herbs and CAM (complementary and alternative medicines) have increased to manage hypertension. A literature review conducted by Zuhal et al. in 2012 suggests that lemon juice may help reduce systolic blood pressure. Tezel et al. conducted a study in 2003 in turkey to assess the therapeutic potential of lemon juice on blood pressure maintenance. The findings of this study support the use of lemon juice as an alternative therapy for decreasing blood pressure. This indicates that consuming lemon juice may help manage blood pressure. However, scientific evidence supporting these claims is limited, and this warrants the need for more clinical studies to support these claims.8
Asthma is a chronic inflammatory disorder of the airways known to impair normal breathing. The use of natural products as a complementary or alternative treatment for asthma has increased. For almost 5000 years, the use of plant-based products as traditional medicine for the treatment of asthma has been reported. Costa et al. conducted a study in 2010 to identify plant-based natural products for managing asthma. This study identified lemon as a potent anti-asthmatic agent. Additionally, lemons may help reduce cough (anti-tussive property). This indicates that lemons may have the potential to manage asthma and may provide symptomatic relief, but we need more scientific evidence to support these claims.3,9
Scurvy is a disease caused by a deficiency of Vitamin C and is characterised by generalised weakness, bleeding and bruising gums, etc. Dr. James Lind was the first physician to conduct a controlled clinical trial in 1796. Due to the high mortality from scurvy amongst the sailors, he planned a comparative trial to assess the effect of citrus fruits like lemons and oranges on scurvy. To his surprise, Lind found that citrus fruits (lemons and oranges) were better than other treatments for scurvy. Additionally, Vitamin C is required to form collagen, which plays an important role in stopping bleeding. Therefore, lemons may help in healing wounds. This indicates that lemons, a rich source of Vitamin C, may help manage scurvy. However, more studies should be conducted to increase the reliability of these results.10,11
Though there are studies that show the benefits of Lemons in various conditions, these are insufficient, and there is a need for further studies to establish the true extent of the benefits of Lemons on human health.
