Organic Aloe

Also known as: Aloe vera, Aloe, Aloe barbadensis Mill.

Overview

Aloe vera, scientifically known as Aloe barbadensis Mill., is a plant from the Liliaceae family widely recognized for its medicinal and cosmetic applications. It is sourced from the leaves of the Aloe vera plant and is available in various forms, including gel, juice, and extracts. Aloe vera is primarily used for wound healing, treating skin conditions, addressing digestive issues, and as a topical moisturizer. It is characterized by its anti-inflammatory, antioxidant, and soothing properties. Research on Aloe vera is extensive, with numerous systematic reviews and meta-analyses available, although the quality and consistency of evidence can vary. Its versatility and natural origin make it a popular choice for both therapeutic and cosmetic purposes. While generally considered safe for topical and moderate oral use, it's essential to be aware of potential side effects and interactions, particularly with medications affecting blood sugar levels. The plant's bioactive compounds contribute to its diverse range of health benefits.

Benefits

Aloe vera offers several evidence-based benefits. It significantly reduces the time to complete wound healing, as shown in multiple meta-analyses, although the strength of evidence varies. Topical application is effective in reducing the severity of diaper dermatitis, with a meta-analysis demonstrating a significant decrease compared to controls. For lactating women, Aloe vera reduces nipple pain and irritation, supported by pooled standard mean differences (SMD) of -0.45 for pain and -0.48 for irritation. Some meta-analyses suggest potential benefits in reducing blood glucose levels, but more robust studies are needed. Additionally, Aloe vera is effective in preventing second-degree infusion phlebitis and chemotherapy-induced phlebitis, with highly suggestive evidence. These benefits are particularly notable for lactating women experiencing nipple pain and irritation and for patients with diaper dermatitis seeking improved skin barrier function and reduced severity of the condition.

How it works

Aloe vera's mechanism of action involves several biological pathways. It exhibits anti-inflammatory activity through compounds that inhibit inflammatory pathways, promoting healing. Its antioxidant properties help reduce oxidative stress and protect tissues from damage. Aloe vera also improves skin barrier function by enhancing skin integrity and reducing trans-epithelial water loss (TEWL). It interacts with the skin, gastrointestinal, and possibly the endocrine systems, influencing blood glucose levels and wound healing. Key bioactive compounds such as aloin, aloe-emodin, and vitamins contribute to its anti-inflammatory and antioxidant effects. Topical application allows direct absorption through the skin, while oral ingestion involves gastrointestinal absorption. The bioavailability of Aloe vera components varies depending on the form and preparation.

Side effects

Aloe vera is generally considered safe when used topically or orally in moderate amounts, but potential side effects should be considered. Common side effects include gastrointestinal upset (nausea, diarrhea) when taken orally and skin irritation or allergic reactions with topical use. Uncommon side effects include hypersensitivity reactions and interactions with medications, particularly those affecting blood sugar levels. Rare side effects may include severe allergic reactions and potential liver or kidney toxicity with prolonged or excessive use, primarily based on animal studies. Drug interactions may occur with diabetes medications due to its potential blood glucose-lowering effects. Contraindications include pregnancy and breastfeeding due to limited research, and known allergies to Aloe vera. Caution is advised for children and the elderly due to limited safety data and potential interactions with other medications.

Dosage

For topical use, Aloe vera is typically applied as needed, with no specific minimum dose. For oral use, dosages vary depending on the condition, often ranging from 100-500 mg per day. For blood glucose control, 500-1000 mg per day may be used, while other uses can vary widely. Topical application is generally considered safe in typical usage amounts. For oral use, caution is advised beyond 1000 mg per day due to potential gastrointestinal side effects and interactions. Topical Aloe vera is applied as needed or according to the specific condition being treated. Oral Aloe vera is typically taken with meals to minimize gastrointestinal side effects. Gel or juice is used for topical application, while capsules or tablets are used for oral consumption. Topical absorption is direct through the skin, while oral absorption can be influenced by gastrointestinal health and the presence of other medications.

FAQs

Is Aloe vera safe to use?

Aloe vera is generally safe, but caution is advised in certain populations and with potential interactions. Monitor for allergic reactions or gastrointestinal side effects.

When and how should I use Aloe vera?

Follow the recommended dosing schedule and application instructions. For oral use, take with meals to minimize side effects. Apply topically as needed.

What results can I expect from using Aloe vera?

Improvements in wound healing, skin conditions, and digestive issues can be expected within weeks. Reduction in nipple pain and irritation in lactating women can be seen within days to weeks.

Is Aloe vera a cure-all?

No, Aloe vera is not a cure-all and should be used under the guidance of healthcare professionals, especially for chronic conditions. It is a supplement, not a replacement for medical treatment.
