Lemon (Nimbu): Uses, Benefits, Side effects By Dr. Smita Barode

Introduction

“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 fruit1,2

Nutritional Value of Lemons

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.  

Properties of Lemons

Scientifically proven properties of C.limon include: 

Potential Uses of Lemons for Overall Health

Some of the potential benefits of lemons are described below. 

1. Potential uses of lemons in obesity

Obesity

Plant constituents like polyphenols may help manage obesity. Fukuchi et al. conducted a study6 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. 

2. Potential uses of lemons in cancer

cancer

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 study7 in 2022 to assess the effect of lemon and ginger administration on breast cancer tumour growth in mouse models. The findings of this study11 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. 

3. Potential uses of lemons for blood pressure

blood pressure

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 suggests8 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. 

4. Potential uses of lemons for asthma

asthma

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 study9 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 claims3

5. Potential uses of lemons in scurvy

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 clinical10 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. 

6. Other potential uses of lemons

Frequently Asked Questions (FAQs)

What is the scientific name of lemons? 

The scientific name of lemons is Citrus limon1

Can lemons help in weight loss? 

Yes, studies show that lemons may help in managing obesity and promoting weight loss. However, scientific evidence to support this claim is limited. Therefore, you should consult a doctor if you have any weight-related issues6

Can lemons help in managing blood pressure?

10 Incredible Health Benefits Of Lemon

Introduction

A hot summer day can take a toll on your body. But a glass of fresh lemonade is the most refreshing drink one can have in summers. Lemonade instantly refreshes and calms your body. The easiest go to drink, that can be made in a few minutes.

Lemon is a flavoured fruit. A small quantity of lemon juice can make its remarkable presence in foods and beverages. Adding few drops of lemon juice to curries, soup or drinks, instantly elevates their taste.

Lemons have been around for years. This round, vibrant fruit from the flowering plant family named Rutaceae is scientifically known as a citrus lemon. This bright yellow coloured citrus fruit has a tangy sour taste due to its richness in citric acid. Though they are available in different shapes and sizes across the planet, lemon has its origin in Assam and other parts of Myanmar and China.

An interesting fact about lemon is that it is a very rich source of Vitamin C. And in 1700s, James Lind found that lemons were very useful in treating a medical condition called scurvy (scurvy is a condition caused by low levels of vitamin C in the body)1

Nutritional Facts about Lemon

Lemon is a rich source of vitamin C and is also enriched with Vitamin B6, copper, potassium, magnesium, zinc, flavonoids, antioxidants and phosphorus. It is low in calories and fat. Vitamin C present in the lemon also helps in the process of iron absorption in the body.

Health Benefits of Lemon

Lemon is a versatile fruit which has several potential health benefits. These include:

1. Supports Heart Health

supports heart health

Lemons are the best source of vitamin C and antioxidants. Research suggests that these two nutrients are beneficial for heart health and help prevent heart disease and stroke. However, certain fibres present in lemon can also help lower some risk factors for heart diseases.

Consuming lemon juice may help reduce high blood pressure. Moreover, lemon contains two plant compounds, hesperidin and diosmin, known to lower cholesterol2. These factors suggest its positive effect for heart health.

2. Helps to Boost Immunity

makes your immunity stronger

We all know that lemon is an immunity-boosting fruit as it contains a high amount of vitamin C and antioxidants. It helps to build the immune system and to fight against the germs that causes common cold and the flu. Patients are often advised to consume lemon cough drops when they are suffering from a throat infection. This is because lemons are naturally endowed with antibacterial properties which will lessen the bacterial effects and bring about relief3,4

3. Helps Improve Digestion

digestion

Lemon contains a high amount of soluble fibres that helps in regular bowel movements and also helps improve digestion. The main fibre present in lemon is pectin which helps to improve gut health by increasing the digestion rate of starch and sugar5.

Ayurveda medicine believes that drinking a glass of water with lemon juice with its pulp in the morning can kick-start your digestion process. It also helps you have a healthy digestive system.

In my experience, your body will be able to absorb more iron from your diet’s plant-based foods if you use lemon. Anaemia, which is characterized by the deficiency of iron in the red blood cells. Among many reasons responsible for it, it is frequently associated with an iron shortage in your diet that may be corrected by maintaining adequate iron levels. So, apart from taking an iron-rich diet, you should include good amount of vitamin C in your diet for better absorption of iron.

Dr. Siddharth Gupta, B.A.M.S, M.D (Ayu)

4. May aid Weight Control

weight

Fully squeezed lemon in a glass of lukewarm water with a tablespoon of honey may help support healthy weight in many. Lemon contains a compound called pectin. It is a fibre that expands after ingestion, making you feel full sooner and longer. It will prevent you from snacking on unhealthy foods that will lead to weight gain. Pectin is present in the lemon pulp, so consuming lemon as a whole is essential5,6

Vitamin C, which supports immune system defence and may aid in the body’s ability to fight illness, can be found in one lemon, providing around half of the daily required dose. Lemons have citrus flavonoids as well. From my perspective, you may lessen your chance of developing brain illness and other degenerative diseases by consuming antioxidants that combat free radicals and have anti-inflammatory properties.

Dr. Rajeev Singh, BAMS

5. Helps to Reduce Cancer Risk

cancer

Lemon and lemon juice are a rich source of vitamin C and antioxidants that help fight against free radicles that can cause deadly diseases like cancer. Animal studies suggest that compounds present in the lemon, limonene and naringenin, have anti-cancer properties. However, human studies are required to observe these effects7.

6. May Help in Oral Disorders

oral health

We all know that vitamin C is an essential vitamin for teeth and gums. And, being a rich source of vitamin C, lemon is beneficial for certain mouth conditions. For instance, in scurvy, which is a type of collagen fibre disease resulting from a lack of vitamin C leading to swollen and gums, lemon is said to be helpful. Also, lemon juice may have painkilling effects when applied locally to areas where there is a toothache. It may also help in reducing inflammation1.

Although believed to be healthy for gum issues, lemon juice contains an acid that, when consumed in large quantities, may erode tooth enamel and result in cavities. I strongly recommend making sure you take lemon juice with enough water to offset the acidity.

Dr. Smita Barode, B.A.M.S, M.S.

7. Can Keep Hypertension in Check

hypertension

As per a study published in the Journal of Nutrition and Metabolism, daily intake of lemon along with 30-60 minutes of brisk walking can keep your high blood pressure in check. Those who consumed lemons, showed reduced signs of hypertension as opposed to those who did not8. Thus, lemon can be used as an adjunct along with medical treatment for high blood pressure.

8. Kidney Stone Prevention

urinary stones

High levels of citric acid present in the fresh fruit as well as the lemon juice concentrate can improve urinary citrate levels two-fold without altering the total urinary volume. Studies have revealed that lemonade or lemon juice concentrate can prevent kidney stones by forming urinary citrate which acts as a preventive method for crystal development9

9. Beneficial for Skin

skin

Lemons contain high amount of vitamin C, which is required to generate collagen. Collagen gives our skin a plump and youthful look. It helps to reduce the fine lines on the face and make your skin clear. Moreover, vitamin C also inhibits melanin production in skin cells thus avoiding pigmentation. It also aids in faster recovery of wounds and avoids easy bruising of skin10.

10. Good for Hair

Hair growth

Lemon is high in vitamin C which boosts collagen and improves hair growth by stimulating hair follicles10,11. If you have been suffering from hair loss you can mix two tablespoons of lemon juice with aloe vera gel and apply this to your scalp 30 minutes before your bath and then wash it off with a gentle hair cleanser.

Although studies have shown beneficial effects of lemon for overall health, further large-scale human trials are needed to confirm these benefits. Nonetheless, this tiny nutrition-packed fruit has been used for centuries in ayurvedic practise and when consumed in moderation, can be a great addition to your diet. However, if you have any medical conditions, it’s best to consult your doctor before including anything new into your routine diet.

Side Effects of Lemon

Anything consumed in excess can have a negative impact on your health. Although it’s very nutritious, excessive lemon juice intake may result in the following adverse effects:
