What is Aloe Vera?

Aloe Vera, scientific name Aloe barbadensis miller, is a succulent plant widely distributed in tropical and subtropical areas. Aloe vera is known for its rich nutritional content and various medicinal properties and is widely used in beauty, health and medical fields.

The leaves of aloe vera are rich in a gel-like substance called aloe vera gel, which contains a variety of vitamins, minerals, enzymes and amino acids, and has many benefits for the skin and health.

Background and history

Aloe vera has been used for thousands of years in traditional medicine in ancient Egypt, China, and India. Known as the "miracle plant" or "universal plant," it is used to treat a variety of ailments such as burns, wounds, gastrointestinal problems, and skin conditions. In modern medicine, aloe vera is widely studied for its various bioactive components.

Aloe vera is a cactus plant that grows in dry tropical areas. It is widely cultivated in subtropical areas around the world, including the southern border areas of Texas, New Mexico, Arizona and California in the United States. Historically, aloe vera has been used for skin conditions and is thought to help improve hair loss and promote wound healing.

health benefits

Promote skin health

Aloe vera has significant moisturizing and repairing properties, promoting healthy skin. Research shows that aloe vera gel can speed wound healing, reduce scarring, and relieve skin inflammation and irritation. A clinical trial showed that aloe vera gel significantly improved the healing process in burn patients. [2]

Aloe vera can also reduce dry skin and increase skin elasticity and radiance. [3]

Clinical studies show that topical application of an aloe vera-based gel twice daily (along with medical soap and tretinoin gel) may improve acne. Additionally, research shows that topical application of aloe vera gel may speed burn healing and reduce burn pain. Aloe vera is also used to treat patients with herpes simplex, lichen planus, and psoriasis. [4]

Improve digestive health

Aloe vera has laxative properties and can improve digestive health. Research shows that aloe vera can stimulate intestinal peristalsis, promote defecation and reduce constipation. A double-blind, placebo-controlled trial showed that constipation patients who took aloe vera experienced significant improvement in their symptoms. [4]

In addition, aloe vera can also reduce gastrointestinal inflammation and promote the repair of gastrointestinal mucosa. [5]

Three studies (a total of 236 adults) evaluated the effects of oral aloe vera on symptoms of irritable bowel syndrome. One study showed a benefit, and two other studies showed no significant benefit of aloe vera compared with placebo. In another small European study, 44 patients with ulcerative colitis were randomized to receive aloe vera gel or a placebo for one month. Nearly half of the people who received aloe vera responded to the treatment, compared with only 14% of the placebo group. [5]

Anti-inflammatory and antibacterial effects

Aloe vera has anti-inflammatory and antibacterial properties that reduce inflammation and bacterial infections in the body. Studies have shown that the polyphenolic compounds and enzymes in aloe vera can inhibit the growth of a variety of pathogenic bacteria and reduce the release of inflammatory mediators. An in vitro study showed that aloe vera has significant inhibitory effects on a variety of bacteria and fungi. [6]

Aloe vera also strengthens the immune system and increases the body's ability to fight infections. [7]

Lower blood sugar and blood lipids

Aloe vera has potential benefits in lowering blood sugar and blood lipid levels. Research shows that aloe vera can improve insulin sensitivity, reduce blood sugar swings, and lower blood lipid levels. A clinical trial showed that diabetic patients who took aloe vera experienced significant reductions in blood sugar and lipid levels. [8]

Aloe vera can also reduce the risk of cardiovascular disease and protect heart health. [9]

Instructions

Take internally

Aloe vera supplements are usually sold in capsule, tablet, or liquid form. Recommended dosage varies by product, but a typical daily dose is 50-200 ml of aloe vera gel or 10-30 ml of aloe vera juice. A doctor should be consulted before use to ensure safety.

external use

Aloe vera gel and serum can be applied directly to the skin to treat burns, wounds, skin inflammation and dryness. Use according to product instructions.

For people

Aloe vera is suitable for people who want to promote skin health, improve digestive problems, anti-inflammatory and antibacterial, and lower blood sugar and blood lipids. However, pregnant women, lactating women and patients with certain diseases should avoid use.

drug interactions

Aloe vera may interact with certain medications, especially the following:

  • Hypoglycemic drugs: such as insulin and oral hypoglycemic drugs (such as metformin). Aloe vera may enhance the effects of blood sugar-lowering medications, causing hypoglycemia. [10]
  • Diuretics: Aloe vera may enhance the effects of diuretics and increase the risk of dehydration and electrolyte imbalance. [11]
  • Laxatives: The laxative effects of aloe vera may interact with other laxatives, increasing the risk of intestinal irritation and electrolyte imbalance. [12]
  • Digoxin: Excessive use of aloe vera milk may increase the risk of adverse reactions from digoxin, a drug used to treat heart problems. [13]

Side effects and disadvantages

Some common side effects of aloe vera include:

  • Gastrointestinal upset: Some people may experience symptoms such as abdominal pain, diarrhea, or constipation after taking aloe vera. [13]
  • Skin allergies: Some people may be allergic to aloe vera and develop a rash, itching, or redness. [14]
  • Hypoglycemia: Aloe vera may enhance the effects of blood sugar-lowering medications, causing symptoms of hypoglycemia such as dizziness, weakness, and heart palpitations. [15]

In addition, long-term or excessive use of aloe vera may cause more serious health problems:

  • Electrolyte Imbalances: The laxative effects of aloe vera may cause electrolyte imbalances, increasing the risk of muscle cramps and cardiac arrhythmias. [16]
  • Intestinal irritation: Long-term use of aloe vera may cause irritation to the intestines, leading to intestinal dysfunction. [17]
  • Liver and kidney burden: Long-term high-dose use of aloe vera may put stress on the liver and kidneys, leading to decreased liver and kidney function. [18]
  • Taking aloe vera milk by mouth may cause abdominal pain and cramping. Oral administration of aloe vera leaf extract (for as little as 3 weeks and as long as 5 years) has been reported to be associated with cases of acute hepatitis. [19]

Animal studies have found that oral administration of aloe vera leaf extract is associated with gastrointestinal cancer in rats and mice; however, studies have raised concerns about differences between the products used and those commonly used by consumers. Therefore, more research is needed to assess its relevance to human health. Both aloe vera gel and milk forms may be unsafe to take by mouth during pregnancy and breastfeeding. [20]

People with liver and kidney disease, low blood sugar, or intestinal problems should avoid using aloe vera and consult a doctor before use.

鐵質(iron)係人體不可或缺嘅微量元素,主要負責攜帶氧氣嘅血紅素(hemoglobin)製造、能量代謝、免疫調節等。當鐵質長期攝取不足、吸收差、或失去過多,就會導致「低鐵」(iron deficiency)甚至發展成「缺鐵性貧血」(iron deficiency anemia)。本文將從臨床醫學與分子生理角度,深入探討低鐵嘅成因、病理機制、生物轉化過程,以及其對人體造成嘅連鎖影響。
