When Herbal Laxatives Go Wrong: Finding The Fine Line

Herbal laxatives are a popular choice for people looking to relieve constipation, but it's important to know when enough is too much. While natural laxatives can be a safe and inexpensive alternative to over-the-counter products, they should not be used as a long-term solution. For example, natural stimulant laxatives like senna tea can cause mild cramping and diarrhea if taken in excess. Furthermore, long-term use of herbal laxatives has been linked to adverse health effects such as liver damage and electrolyte deficiency. To avoid these risks, it's recommended that individuals only use herbal laxatives for short periods and in the correct doses.

Senna tea: a gentle laxative, but can cause liver damage in high doses

Senna tea is a herbal medicine made from the leaves, flowers, and fruit of the legume family of plants. It is commonly used as a laxative to treat constipation and is approved by the FDA as a non-prescription drug for this purpose. Senna is also used to clear the system before certain medical tests, such as a colonoscopy.

The active compounds in senna leaves are known as senna glycosides, or sennosides, which cannot be absorbed by the digestive tract. Instead, they are broken down by gut bacteria, mildly irritating the cells in the colon and stimulating intestinal movement.

While generally considered safe for most adults and children over the age of 12, senna tea does come with some risks and side effects. The most common side effects are stomach cramps, nausea, and diarrhoea. Senna tea should not be used for more than 7 consecutive days unless otherwise directed by a healthcare provider. Long-term use may lead to laxative dependence, electrolyte disturbances, and liver damage.

The typical dose of a senna-based supplement is 15–30 mg per day for no longer than one week. However, there is no clear dosing recommendation for senna tea, as the concentration of sennosides varies depending on how long the tea is steeped.

Aloe vera: packed with enzymes, vitamins, minerals and electrolytes that aid the gut

Aloe vera is a medicinal plant that has been used for thousands of years for its health, beauty, and skincare properties. It is packed with enzymes, vitamins, minerals, and electrolytes that aid the gut.

The inner gel of the aloe vera leaf contains 99% water, with the remaining 1% consisting of glucomannans, amino acids, lipids, sterols, and vitamins. The middle layer of latex contains bitter yellow sap, which includes anthraquinones and glycosides. Anthraquinones are phenolic compounds traditionally known as laxatives. The outer layer, or rind, has a protective function and synthesizes carbohydrates and proteins.

Aloe vera is commonly used as a natural laxative. The anthraquinones in the latex increase intestinal water content, stimulate mucus secretion, and increase intestinal peristalsis, making it easier to pass bowel movements. The latex also contains a compound called aloin, which acts like a laxative and can irritate the gastrointestinal tract. For this reason, aloin-free aloe vera products are available.

Aloe vera is also believed to have anti-inflammatory components that reduce swelling and improve the function of digestive organs. It may also help normalize acid/alkaline and pH balance, lessen yeast formation, and encourage the growth of good digestive bacteria.

For constipation, it is recommended to take 100-200 milligrams of aloe vera daily. However, it is important to note that high oral doses of aloe vera extract or aloe vera latex can be dangerous and may cause side effects such as abdominal cramps, diarrhea, kidney damage, and electrolyte imbalance. Aloe vera is not recommended for pregnant or breastfeeding women and should not be used by children under 12.

While aloe vera has been used for various health purposes, more research is needed to confirm its effectiveness and safety for certain conditions. It is always important to consult a healthcare professional before taking any herbal remedies or supplements.

Cascara sagrada: a botanical laxative that may cause abdominal pain or electrolyte imbalance

Cascara sagrada is a botanical laxative derived from the bark of the Rhamnus purshiana tree, also known as the California buckthorn. It was once a common ingredient in over-the-counter (OTC) laxatives, but in 2002, the US Food and Drug Administration (FDA) ruled that it was not safe or effective for this use. It can still be purchased as an herbal supplement, but it is not recommended for long-term use due to the risk of serious side effects.

Abdominal Pain

When used to treat severe constipation, cascara sagrada may cause abdominal pain and cramping. This is especially true if it is used for longer than one week. For this reason, it is not recommended for individuals with gastrointestinal disorders such as intestinal obstruction, ulcerative colitis, Crohn's disease, or unexplained stomach pain.

Electrolyte Imbalance

Cascara sagrada works by slowing down water absorption and increasing stool volume. This stimulates muscle contractions in the colon, speeding the clearance of the bowel. However, this mechanism can also lead to dehydration and the rapid loss of electrolytes, including sodium, potassium, and chloride. Electrolyte imbalance can cause a range of serious side effects, including:

• Muscle weakness, spasms, or cramps
• Irregular heartbeat (arrhythmia)
• Skipped heartbeats (palpitations)
• Rapid heartbeat (tachycardia)
• Numbness or tingling of the hands or feet (neuropathy)
• Reduced urine output

Castor oil: a natural, mild stimulant laxative that can be used orally or as an enema

Castor oil is a natural, mild stimulant laxative that can be used orally or as an enema. It is a low-priced, effective option for treating constipation, and has been used as such for thousands of years. The oil is derived from the castor plant, and is available at most pharmacies and health food stores.

When taken orally, castor oil stimulates the bowel to move more, encouraging the stool to pass through the intestine and out of the rectum. It typically causes a bowel movement to occur in 2 to 3 hours, but it may take up to 6 to 12 hours to work for some people. Due to its delayed effects, it is not recommended to take castor oil before bedtime. It is important to note that overuse of castor oil may affect the ability of the bowel muscles to work effectively.

As an enema, castor oil is inserted into the rectum, where it lubricates the bowels and makes it easier to pass a bowel movement without straining.

The typical dose of castor oil for adults and children over the age of 12 is between 15 to 60 milliliters (ml) per day, which is equal to about half an ounce or 3 teaspoons. It is recommended to take this dose on an empty stomach, and it can be mixed with juice to improve the taste. Castor oil has a very strong flavour, so it is often mixed with other liquids or bought as a flavoured preparation.

Castor oil is not suitable for everyone and should not be used long-term. It is not recommended for pregnant people, regular use in children under 12, adults over 60, or those with certain health conditions such as inflammatory bowel disease (IBD) or appendicitis. It may also interact with certain medications, including diuretics and antibiotics.

Mineral oil: a lubricant laxative that can be taken orally or used as an enema

Mineral oil is a lubricant laxative that can be taken orally or used as an enema. It is used to treat constipation by coating the stool and the inside of the bowel with moisture, preventing the stool from drying out. This helps to keep the stool soft and makes it easier to pass through the intestines. It is generally considered safe and effective and has been used for many years.

Mineral oil is available in liquid or oral form, as well as an enema. The oral form can be taken as directed by a doctor or as indicated on the product package. It is important to carefully measure the dose using a special measuring device or spoon, as household spoons may not provide an accurate dose. It should also be taken on an empty stomach, as it can interfere with the absorption of certain vitamins and other medications. It is recommended to take mineral oil at least two hours before or after taking other medications.

The dosage of mineral oil varies depending on age and medical condition. For children under six, the oral dose ranges from 15 to 30 milliliters (ml). Some doctors recommend against giving mineral oil to children under six. For adults, the oral dose ranges from 15 to 45 ml. It is important to follow the instructions carefully and not exceed the recommended dosage or duration of use.

Mineral oil usually takes about 6 to 8 hours to work, so it is often taken before bedtime to reduce the chance of waking up during the night to go to the bathroom. It should not be taken for more than 7 days unless directed by a doctor. It is also important to note that mineral oil may leak from the rectum, especially at high doses, and can cause irritation or itching.

While mineral oil is generally considered safe, it is not recommended for older adults, children under six, or bedridden individuals. It should also be used with caution during pregnancy, as it can interfere with nutrient absorption. If respiratory problems, such as coughing, develop after taking mineral oil, medical attention should be sought.
