Aloe vera is a plant species that belongs to the Xanthorrhoeaceae family and is native to Africa and the Arabian Peninsula. It is widely grown as an ornamental plant in gardens or kept indoors in pots. Its leaves contain compounds with medicinal properties, which is why it is used to treat various skin problems and other ailments.

Aloe vera has been used for medical reasons since ancient times. Even Hippocrates wrote about its cosmetic and healing effects on wounds and burns in 500 BCE. Recent studies have shown that active compounds like polysaccharides, glycoproteins, and anthraquinones in aloe vera are useful for treating burns, sunburns, abrasions, cuts, eczema, and psoriasis. There is also some evidence that aloe vera can help with gastrointestinal disorders such as irritable bowel syndrome (IBS). But more research is needed to confirm these findings.

History Of Aloe Vera

It is believed to have originated in the Arabian Peninsula and was introduced to Egypt in the 6th century BC, where it was known as the ‘plant of immortality’. From medieval times, Arab physicians used aloe to treat various illnesses, while Europeans used it to heal wounds, reduce fever and improve digestive health.

During WW2, soldiers even took aloe leaves with them into battle due to their antiseptic qualities. Today, more than 200 species of aloe are still used medicinally around the world due to its anti-inflammatory effects and other benefits. Modern science continues to research the therapeutic potentials of aloe vera for humans and animals.

(1) Potential Contraindications

Although aloe vera is widely known for its many medicinal properties, it has several potential contraindications and side effects. It is important to take caution when using this herbal remedy as certain drug interactions can occur with other medications.

Additionally, some people may experience adverse reactions such as abdominal cramps or diarrhea when ingesting the plant’s juice or gel form. Prolonged use of aloe vera products may also cause kidney damage in rare cases.

It is essential to consult a healthcare professional before taking any dietary supplements containing aloe vera extracts due to the risks associated with their usage.

Moreover, pregnant women should be especially cautious as consuming large quantities of Aloe Vera could lead to uterine contractions, which would increase the risk of miscarriage. Therefore, it is always advised to consume this herb in moderation under the guidance of a qualified medical practitioner.

(2) Skin Reactions

Despite numerous benefits, aloe vera can cause some skin reactions when used topically or orally.

Skin irritation is the most common side effect of topical aloe application, and may manifest as itching, redness, swelling, burning sensation, dryness, or rash. In severe cases, it can even lead to hypersensitivity reactions with symptoms such as hives and skin allergies.

Additionally, oral consumption has been known to cause allergic contact dermatitis in people who are sensitive to latex. This reaction typically appears as a localized rash that is more intense than other types of skin irritation from aloe vera use.

It is important for individuals using aloe products to be aware of potential skin reactions associated with their usage. If any adverse effects occur after using an aloe product on the skin or ingesting it by mouth, medical advice should be sought immediately.

(3) Digestive System Effects

Consuming aloe vera orally can lead to mild to moderate digestive discomforts, such as bloating and flatulence. If the concentration of aloe latex is too high, more serious symptoms can occur, including vomiting, abdominal pain, and bloody or mucus-filled loose stools.

Long-term exposure to oral doses of aloe should be avoided as it may cause electrolyte imbalances. Drinking too much aloe juice can also cause dehydration due to its laxative effects. Therefore, it’s best not to exceed recommended dosages without consulting a doctor.

To avoid any potential harm, individuals should be careful when taking aloe vera supplements. They should follow the suggested dosage and not exceed it without consulting with a medical professional.

In addition, those with underlying health conditions should also speak to their physicians before taking any supplement containing aloe vera extracts to avoid any potential interactions with their current medications.

(4) Blood Sugar Level Effects

Aloe vera has been shown to affect blood sugar levels.

Studies suggest that consuming aloe vera can help lower fasting and post-meal plasma glucose, increase insulin sensitivity, and improve glycemic control in those with diabetes or pre-diabetes.

Aloe vera may also be beneficial in managing hyperglycemia, as it can help reduce elevated serum glucose concentrations and hemoglobin A1c concentrations. As such, aloe vera could be a useful tool in the treatment of diabetes and high blood sugar levels.

(5) Possible Allergies

Aloe vera is known for its many potential health benefits, however, it can also lead to allergies in some individuals. Allergic reactions to aloe vera can arise from topical application or ingestion of aloe vera products and can range from mild dermatitis to life-threatening anaphylaxis.

(6) Interaction With Medication

Interactions between aloe vera products and medication should be discussed with a healthcare professional before use.

Here are some of the possible interactions to consider:

1. Digoxin: Concomitant administration of digoxin with aloe vera has been associated with an increased risk for adverse effects on heart rate.

4. Further research: Further research needs to be conducted regarding the precise mechanism behind medication-aloe interactions before any definite conclusions can be made about how this plant interacts with drugs.

(7) Pregnancy And Breastfeeding Considerations

Aloe vera is a natural product with many potential benefits. However, the use of aloe vera during pregnancy and breastfeeding is not recommended due to a lack of evidence regarding safety for pregnant or nursing mothers or their babies. Not enough research has been conducted on aloe vera’s effects in these populations.

Therefore, it is best for pregnant women and those who are breastfeeding to avoid consuming aloe vera products orally or topically without consulting a healthcare provider first. If considering using an aloe vera product while breastfeeding, the area where the gel was applied must be washed off before feeding the baby.

While there have been no reports of adverse events associated with topical exposure to aloe vera among breastfed infants, more studies should be conducted to ensure safety when used by lactating mothers.

(8) Long-Term Effects

The long-term effects of aloe vera are not well known, as there have been few studies conducted on extended use or chronic consumption. While the short-term effects of oral intake of aloe vera seem to be generally safe and beneficial, more research is needed to identify any potential side effects that may occur with long-term exposure.

Studies suggest that when taken orally at recommended doses over an extended period, aloe vera has several health benefits including improved digestion, reduced inflammation, and antioxidant activity.

However, it is important to note that these findings cannot be applied to chronic use or extended consumption without further study. Aloe vera should only be used for its intended purpose and by directions provided by your healthcare provider. It is advisable to consult with your doctor before taking aloe vera regularly for longer than two weeks.

Dosage Guidelines

Aloe vera has been widely studied and has been found to have many positive long-term effects. However, it is important to consider dosage guidelines when taking aloe vera as a supplement or topical treatment. It is recommended to speak to a healthcare provider before beginning any new diet, especially one that contains aloe vera.

For oral intake, the recommended dosage ranges from 150 milligrams (mg) up to 1 gram (g). For external use, manufacturers suggest applying it once per day for best results, but some studies suggest twice a day depending on the severity of the symptoms. It is suggested not to exceed 500 mg per day when taken orally and 5% concentration when applied externally. Additionally, it is advised to discontinue usage after two weeks to avoid any potential negative side effects.

When using aloe vera, it is best to start with lower doses and gradually increase them as needed. It is important to pay attention to any signs of allergic reactions or other negative side effects. Carefully monitoring individual responses will help ensure successful incorporation into an existing wellness routine without any health issues.
