Senna

What is Senna?

Senna is a natural herb that has been used for centuries due to its laxative properties. It comes from the leaves and pods of the Senna plant, which is native to countries in the Middle East and Africa. Senna is commonly consumed as a tea or taken in the form of capsules or tablets.

As a dietitian, I often get questions about senna and its effectiveness as a weight loss aid. While senna is known for its ability to relieve constipation and promote bowel movements, it is important to understand that it is not a weight loss miracle drug.

Senna works by stimulating the muscles in the intestines, causing them to contract and push stool through the digestive tract. This can provide temporary relief from constipation. However, the weight loss that may result from using senna is primarily due to water loss and increased bowel movements. It does not lead to long-term fat loss or provide any lasting benefits for weight management.

What are the benefits of Senna?

Senna is a plant native to tropical regions and has been traditionally used for its laxative properties. In this article, I will discuss the health benefits of senna, including its potential role in relieving constipation, promoting weight loss, and supporting detoxification.

Relieving Constipation

Senna is most commonly known for its potent laxative effects, which can help relieve constipation. The active compounds in senna, known as anthraquinones, stimulate the muscles in the intestines, promoting bowel movements. As a result, senna may be a useful option for individuals who struggle with occasional constipation.

According to a systematic review published in the Journal of Ethnopharmacology, senna was found to be effective in increasing stool frequency, softening stool consistency, and reducing the time taken for the first bowel movement in individuals with constipation. However, it is important to note that long-term use of senna as a laxative should be done under the guidance of a healthcare professional, as it may lead to dependence or other adverse effects.

Promoting Weight Loss

In addition to its role in relieving constipation, senna has also been associated with weight loss. It is important to note that senna should not be used as a standalone weight loss solution, but rather as a complementary strategy alongside a healthy diet and regular exercise.

Some research suggests that the laxative effect of senna may help individuals eliminate excess waste and water weight, which can contribute to temporary weight loss. However, this weight loss is likely to be short-term and may not be sustainable in the long run.

Supporting Detoxification

Another potential benefit of senna is its ability to support detoxification. Detoxification refers to the body’s natural process of eliminating toxins and waste products. While the body has its own detoxification systems, some believe that certain herbs, such as senna, may help enhance these processes.

A study published in the Journal of Pharmacy and Pharmacology investigated the detoxifying effects of senna in rats and found that it exhibited significant antioxidant activity, which may help protect against oxidative stress and support overall detoxification processes. However, more research is needed to fully understand the impact of senna on human detoxification.

What are the Side-effects of Senna?

Senna is commonly used to treat constipation and promote bowel movements. While it can be effective in providing relief, it is essential to be aware of its potential side-effects.

One of the most common side-effects of Senna is abdominal discomfort or cramping. This is because Senna stimulates the muscles in the intestines, causing them to contract and propel waste through the digestive system. Some individuals may experience mild to moderate abdominal pain or cramping after taking Senna. This discomfort is usually temporary and resolves on its own as the body adjusts to the herb.

Another potential side-effect of Senna is diarrhea. This is an expected outcome of the increased intestinal muscle activity caused by Senna. While this may be beneficial for those suffering from constipation, it can be an inconvenience for others. It is important to maintain proper fluid intake to prevent dehydration and replenish electrolytes lost due to diarrhea. It is always recommended to consult with a healthcare professional or dietitian before using Senna to determine the appropriate dosage and duration of use.

In some cases, individuals may develop an allergic reaction to Senna. This can manifest as itching, hives, or a rash. Severe allergies may lead to difficulty breathing, swelling of the face, or dizziness. If any signs of an allergic reaction occur, it is important to seek immediate medical attention.

Long-term use of Senna can potentially lead to dependence or a condition known as “lazy bowel.” This is when the bowel becomes reliant on the stimulant properties of Senna to produce regular bowel movements. Over time, the body may lose its natural ability to eliminate waste without the aid of Senna, leading to a cycle of dependence. It is recommended to use Senna intermittently and not exceed the recommended dosage to avoid this potential side-effect.

What are the various types of Senna?

There are several different types of Senna, each with its own unique properties and potential health benefits. Let’s explore a few of the most common types and their uses.

1. Cassia angustifolia: Also known as Indian Senna or Tinnevelly Senna, this is perhaps the most well-known and widely used type of Senna. It has been traditionally used as a natural remedy for constipation, promoting bowel movements by stimulating the muscles in the intestines. Cassia angustifolia contains compounds called anthraquinones, which have laxative effects. It is available in various forms such as tea bags, capsules, or dried leaves, and can be found in some over-the-counter laxative products.

2. Cassia acutifolia: Commonly referred to as Alexandrian Senna or Khartoum Senna, this type of Senna is native to the African continent. It is known for its potent laxative properties and is often used in the form of herbal tea or powder. Cassia acutifolia contains similar anthraquinone compounds as Cassia angustifolia, making it effective in promoting bowel movements and relieving occasional constipation. However, it is important to note that prolonged or excessive use of Senna can lead to dependence and gastrointestinal disturbances, so it should be used under the guidance of a healthcare professional.

3. Cassia obovata: Also known as neutral or blonde Senna, this type of Senna has different properties compared to Cassia angustifolia and Cassia acutifolia. It is primarily used for its hair conditioning and coloring properties. Cassia obovata powders or pastes are often used as a natural treatment for promoting hair growth, enhancing shine, and adding a reddish tint to the hair. This type of Senna does not possess the same strong laxative effects as the previously mentioned types, so it is not commonly used for addressing digestive issues.

4. Senna occidentalis: This type of Senna, commonly known as Negro coffee or coffeeweed, is native to tropical regions and has a history of traditional use. Senna occidentalis is not primarily used for its laxative properties but rather for its potential anti-inflammatory and antimicrobial effects. It has been studied for its potential in the treatment of skin conditions, such as eczema and dermatitis, as well as for its antioxidant activity. However, further research is needed to fully understand its potential health benefits and to determine safe and effective dosages.

5. Senna tora: Another type of Senna found in tropical areas, Senna tora is sometimes referred to as Sickelpod Senna or sickle bush. Like Cassia obovata, it is not commonly used for its laxative properties. Instead, Senna tora has been traditionally used for its potential antimicrobial, anti-inflammatory, and antioxidant effects. It has also shown promise in supporting liver health and has been used in traditional Ayurvedic medicine for detoxification purposes. However, as with any herbal remedy, it is essential to consult with a healthcare professional before using Senna tora or any other form of Senna for therapeutic purposes.

How does Senna work?

Senna is a natural herbal laxative derived from the leaves and pods of the Senna plant, also known as Cassia Angustifolia. This plant contains compounds known as sennosides, specifically sennosides A and B, that have a laxative effect on the body.

When you consume Senna, these sennosides are passed through your digestive system and reach your large intestine, also known as the colon. Once in the colon, the sennosides influence the muscle contractions there. These contractions, which are responsible for moving waste through your digestive tract, are stimulated by the sennosides. As a result, the muscles contract more forcefully and frequently, speeding up the movement of stool through the colon.

Another way Senna helps with constipation is by increasing the amount of water and electrolytes, such as potassium and sodium, that are secreted into the colon. This additional water softens the stool, making it easier to pass and effectively relieving constipation.

It is important to note that Senna is generally a short-term solution used for occasional constipation relief. It is not recommended for long-term use, as your body may become dependent on it to produce bowel movements. Long-term use of Senna can also lead to electrolyte imbalances and dehydration.

Since Senna is available in various forms like tablets, capsules, and teas, you might be wondering which one is best for you. The choice ultimately depends on your personal preference and needs. The tablets and capsules are convenient and easy to take, while teas can have a more gentle and soothing effect on the digestive system.

If you are considering using Senna, it is crucial to consult with a healthcare professional, such as a doctor or a pharmacist. They can help determine the appropriate dosage and duration for your specific situation.

Recommended dosage of Senna

The appropriate dosage of Senna can vary depending on factors such as age, gender, individual needs, and overall health goals. To begin, it is recommended to start with the lowest effective dosage and gradually increase if needed. A typical starting point is 17.2 milligrams of Senna extract per day, which can be increased up to 34.4 milligrams if necessary.

Adults

For adults, the dosage of Senna may differ based on individual requirements. The general guideline for adults is to take 17.2 milligrams to 34.4 milligrams of Senna extract per day, based on the severity of constipation. However, it is crucial to remember that Senna should not be used for more than seven consecutive days without seeking medical advice.

Children

When it comes to children, caution is even more crucial. Senna is not recommended for children under the age of 12, as their bodies are still developing and may react differently to the medication. In cases where children experience constipation, it is best to consult a pediatrician or a healthcare professional for appropriate solutions.

Elderly

For elderly individuals, who often struggle with constipation due to various health issues or medications, the dosage of Senna should be approached with care. It is recommended to start with the lowest effective dosage and closely monitor the response. Consulting a healthcare professional is advisable to ensure the dosage is appropriate for the specific health condition and any potential interactions with other medications.

Health Goals

While Senna may be effective in providing relief from constipation, it is important to remember that it should not replace a balanced diet and a healthy lifestyle. To achieve long-term health goals, focus on incorporating a variety of fiber-rich foods, regular physical activity, and staying hydrated. Relying solely on laxatives for bowel movements may hinder the body’s natural mechanisms and create dependency.
