What is Lauki (Bottle Gourd)?

Introduction

It may not be the most exciting vegetable in your kitchen, but bottle gourd, or lauki, is one of the most underrated health boosters in Indian households.

Used in everything from curries and soups to halwas and juices, this humble green veggie packs more benefits than you’d expect.

From heart and liver support to aiding weight loss and digestion, lauki has been part of traditional medicine and modern diets alike. But is it always safe? Can bitter lauki really be toxic? Let’s explore what science says about its nutritional value, benefits, and potential side effects.

What is Lauki (Bottle Gourd)?

The benefits of green vegetables are known to everyone. And bottle gourd, commonly known as lauki, is a vegetable with many health benefits. It is known by various names, including white-flowered gourd, calabash, New Guinea bean, Tasmania bean, and long melon. It belongs to the gourd family, Cucurbitaceae, and is a vine that runs or climbs. Bottle gourds come in various shapes: small and bottle-shaped, huge and round, or slim and twisty.

Bottle Gourd Nutrition Value 100 gm

Bottle gourd contains 96.1% water, so is light on the stomach and aids digestion. It helps lose weight quickly because of its high dietary fiber and low fat and cholesterol content. It is also packed with Vitamin A, B, and C and essential minerals. Here is the bottle gourd nutritional value:

Scientifically Supported Benefits of Bottle Gourd (Lauki)

Backed by modern nutritional science, these benefits of bottle gourd are well-established and relevant to everyday health concerns:

Hydration & Cooling

Why it matters: Staying hydrated is crucial for maintaining optimal health, including temperature regulation, skin health, and digestion.

With a water content of more than 96%, the bottle gourd is a natural hydrator. It helps replenish fluids lost through sweat, especially during hot summer months, and is often recommended in Ayurveda to cool down the body and calm internal heat. Unlike sugary packaged drinks, lauki juice offers hydration without extra calories or additives. This makes it an ideal choice for people prone to heat-related fatigue, dehydration, or urinary infections.

Weight Management

Why it matters: Obesity is linked to conditions like diabetes, heart disease, and joint pain. Managing weight through nutrient-dense foods is a key strategy.

Bottle gourd is extremely low in calories (15 kcal per 100g) and contains dietary fibre, which increases satiety and slows down digestion, thereby reducing the urge to snack unnecessarily. It is also virtually fat-free and cholesterol-free. When consumed as a part of a high-fibre diet, lauki supports weight loss by promoting fullness without compromising on essential nutrients. That’s why it’s often included in detox diets, low-calorie soups, and juices.

Heart Health Support

Why it matters: High blood pressure and cholesterol are two of the most significant risk factors for heart disease.

Lauki is a natural source of potassium (170 mg/100 g) and magnesium (11 mg/100 g)—two minerals that play a crucial role in regulating blood pressure, reducing arterial stiffness, and supporting proper heart rhythm. Its low sodium content (just 2 mg per 100 g) makes it an excellent food choice for people with hypertension. Regular consumption, as part of a balanced diet, can help reduce cardiovascular risk factors and promote better long-term heart health.

Digestive & Diuretic Properties

Why it matters: Poor digestion can impact immunity, energy levels, and skin health, while water retention can lead to bloating and stress on the kidneys.

Lauki contains 1.2 g of fibre per 100 g, which helps regulate bowel movements, reduce constipation, and improve gut motility. It also acts as a mild natural diuretic, helping increase urine output, which supports kidney function and aids in flushing out toxins from the body. This is especially useful for people prone to urinary tract infections (UTIs), bloating, or those looking to maintain a healthy fluid balance. Lauki is gentle on the stomach, making it a safe choice for people with acidity or IBS.

Traditional Uses of Bottle Gourd (With Important Cautions)

Beyond its scientifically supported benefits, the bottle gourd has also held a place in traditional Indian medicine for various uses. While many of these claims are based on Ayurvedic wisdom and anecdotal experience, it’s essential to approach them with care, especially if you’re managing a medical condition.

Mental Calmness and Sleep Support

Traditionally, bottle gourd is considered a sattvic food, believed to promote calmness and clarity of mind. Some remedies even suggest combining lauki juice with sesame oil to improve sleep quality. While this may have a calming effect for some, individuals with chronic insomnia or other sleep disorders should speak to a doctor before relying on such remedies.

Hair Health and Premature Greying

Culturally, bottle gourd juice has been used in home remedies to improve hair texture and slow down premature greying. Crushed leaves are also applied to the scalp in some traditions. However, these uses are anecdotal—there is no clinical evidence to support lauki as a proven remedy for hair loss, baldness, or greying.

Mental Wellness Support

Some sources refer to lauki as a natural “nerve tonic,” suggesting it may help with stress or cognitive balance. This idea is grounded in traditional medicine, but not in modern neuroscience. Lauki should not be used as a treatment for mental health disorders such as OCD, depression, or anxiety, which require expert diagnosis and medical care.

Respiratory Health

Thanks to its high water content and anti-inflammatory nutrients, lauki may support general respiratory wellness. In traditional practice, it has been used to help soothe symptoms of cough or breathing discomfort. However, there is no direct evidence that it treats bronchitis, asthma, or other chronic respiratory conditions. Always consult your doctor before using it for such purposes.

Reminder: Traditional remedies can be a supportive part of your lifestyle, but they are not substitutes for clinical treatment. Always consult a healthcare provider before using any food or herb as a remedy for diagnosed medical conditions.

Daily Consumption Limit of Bottle Gourd

The daily consumption limit of bottle gourd should be moderated to ensure safety and health benefits. It is recommended to drink no more than 1 cup (about 250 ml) of fresh bottle gourd juice per day. Consuming more can potentially cause toxicity, especially if the gourd is bitter.If you are having it cooked, consume approximately 1-2 cups (200-300 grams) daily.

Side Effects of Bottle Gourd

The following are some of the lauki juice side effects:

•   Research has shown that consuming bitter bottle gourd juice can be highly toxic to the body. 23 confirmed cases of bottle gourd poisoning were recorded in a single year due to bitter-tasting juice ingestion.

It may also cause various side effects, such as diarrhoea, nausea, vomiting, discomfort, or any feeling of uneasiness. Therefore, it is essential to taste the juice before consuming it.

• Bitter bottle gourd contains toxic compounds called cucurbitacins, which can cause serious gastrointestinal problems, including stomach pain, vomiting, ulcers, and inflammation of the stomach lining and oesophagus. In severe cases, it can even lead to internal bleeding and require immediate medical attention. Always taste a small piece before juicing—if it’s bitter, discard it immediately.
• Bottle gourd juice has a low glycemic index and may help lower blood sugar. However, consuming excessive amounts, especially by individuals who already have low blood sugar levels or are on diabetes medication, may increase the risk of hypoglycemia. Stick to the recommended intake—no more than 1 cup (250 ml) per day—and avoid drinking it on an empty stomach without medical guidance.
