Science-Based Health Benefits from Sabila

Sabila Mechanism of action in disease prevention

Sabila has several active constituents and most of them have therapeutic implications for disease prevention and treatment through the modulation of various biological and genetic activities. The possible mechanisms of actions of Sabila are described as follows:

  1. Sabila has aloe-emodin (AE), aloin (barbaloin), anthracene, and emodin found to be relevant to cancer prevention owing to the activation and inactivation of molecular pathways associated with them.
  2. Sabila functions as an antioxidant through free radical and superoxide radical-scavenging activities and anti-inflammatory activities via inhibition of prostaglandin E2 production from arachidonic acid and also inhibition of various transcription factors and the activities of enzymes including lipoxygenase and cyclooxygenase.
  3. Sabila shows antimicrobial activity by rupturing bacterial cell walls. Earlier studies have reported the anti-inflammatory and antibacterial properties of Sabila gel. Source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4557234/

Sabila has Anti Leukemic Function through its Anti-Mutagenic Activity

A study that isolated di(2)-Ethylhexyl)phthalate (DEHP) from Sabila found that Sabila exhibited growth inhibition against three leukemic cell lines and reduced AF-2-induced mutagenicity. DEHP was considered the active principle responsible for the anti-leukemic and anti-mutagenic effects in vitro.

Sabila has Wound Healing, Anti-cancer, and Immune stimulation Activities

The study isolated a major carbohydrate fraction from the gel of Aloe vera leaf. It has been claimed to accelerate wound healing, immune stimulation and have anti-cancer and anti-viral effects. The study showed acemannan an extract found from Aloe vera stimulates cytokine production, nitric oxide release. The production of cytokines IL-6 and TNF-alpha were acemannan dose-dependent. The results suggest acemannan may function, in part, through macrophage activation.

Aloe Vera, Promotes Bone Regeneration and Formation (osteoformation)

Studies suggest that acemannan, a polysaccharide extracted from Aloe vera gel, could affect bone formation.  Acemannan could function as a bioactive molecule inducing bone formation by stimulating BMSCs proliferation, differentiation into osteoblasts, and extracellular matrix synthesis. Acemannan extracted from Aloe vera could be a candidate for natural biomaterial for bone regeneration.

Aloe Vera for Biochemotherapy: An effective support for Chemotherapy

The study showed the percentage of both objective tumor regressions and disease control was significantly higher in patients concomitantly treated with Aloe than with chemotherapy alone. Studies suggest Aloe may be beneficial to use with chemotherapy to increase efficacy in terms of both tumor regression and survival time.

Sabila as Antigenotoxic

The study showed antigenotoxic potentials of aloe and suggests a potential use in the prevention of DNA damage caused by chemical agents.

Aloe-emodin / Anticancer / Antiproliferative :

The study showed aloe-emodin inhibited cell proliferation and induced apoptosis in two human liver cancer cell lines, but with different antiproliferative mechanisms. Results suggest aloe-emodin may be useful in liver cancer prevention.

Sabila Preparations, Usage, and Side Effects

Sabila Preparation and Usage

Sabila leaves contain a clear gel that is often used as a topical ointment.

The green part of the Aloe leaf that surrounds the gel can be used to produce a juice or a dried substance (called latex) that is taken by mouth.

Sabila Warnings and Side Effects

  • Use of topical Sabila is not associated with significant side effects.
  • A 2-year National Toxicology Program (NTP) study on oral consumption of non-decolorized whole leaf extract of Sabila found clear evidence of carcinogenic activity in male and female rats, based on tumors of the large intestine. According to the NTP, from what is known right now there is nothing that would lead them to believe that these findings are not relevant to humans. However, more information, including how individuals use different types of Sabila products, is needed to determine the potential risks to humans.
  • Abdominal cramps and diarrhea have been reported with oral use of Sabila.
  • Diarrhea, caused by the laxative effect of oral Sabila, can decrease the absorption of many drugs.
  • People with diabetes who use glucose-lowering medication should be cautious if also taking Sabila by mouth because preliminary studies suggest aloe may lower blood glucose levels.
  • There have been a few case reports of acute hepatitis from Sabila taken orally. However, the evidence is not definitive.
