Examining the healing mystery of Aloe

26.06.2002


If grandma gets a bedsore, the best thing to put on it might be a plant that’s been used for 5,000 years.

The mysterious Aloe vera has been a source for healing since Old Testament times, and a Texas A&M University researcher is trying to uncover just what the substances are in the plant that work wonders and how they do it so that more might be learned about treating wounds.

Dr. Ian Tizard, a professor of immunology in the College of Veterinary Medicine, is studying a special polysaccharide, the substance that forms along cell walls of the Aloe vera, to see how it performs its healing tricks.



The Aloe vera is native to North Africa but now can be found almost worldwide, Tizard says. A succulent, it thrives in warm and dry climates very much like cactus does.

But unlike its prickly cactus cousin, Aloe vera is in a class by itself when it comes to certain healing properties.

There are more than 100 species of aloe, but Tizard says Aloe vera is the one that has drawn the most scientific interest.

"When Aloe vera is placed on many types of wounds, such as bedsores, it can often heal the wound quickly, and the likely reason why is the special polysaccharide in it," Tizard explains.

"Many plants contain this polysaccharide, but the kind found in Aloe vera works differently, we’ve learned. It seems to bind growth factors in wounds whereas normally they would be destroyed. Aloe vera polysaccharide seems to speed along the healing process much quicker.

"How it does this, that’s what we’re trying to find out."

Aloe vera (aloe is an Arabic word for a bitter substance, vera is Latin for truth) has long, pointed leaves consisting of green rind and clear pulp. The pulp is the part of the plant that has the healing agents in it.

"It comes out of the plant like a clear liquid, but when it touches human skin, it becomes a gel," Tizard says. "It acts as a wound sealant in this gel state, and no other plants do so."

Especially benefiting from such treatments could be the elderly, who are susceptible to bedsores, diabetic ulcers and vascular (circulation) ulcers.

"Geriatric patients often have wounds that won’t heal properly or take longer to heal," Tizard says. "That’s one of the things we’re looking at - how can wounds heal quicker, and what role does the Aloe vera plant play in this quicker healing process?"

There’s not much of the Aloe vera plant that isn’t useful, Tizard notes.

The rind of the plant has been used as a laxative while the pulp has been put on burns and wounds for thousands of years. Besides being used in lotions and medicines, in recent years cosmetic companies have used Aloe vera in a variety of products, especially moisturizers.

Im Focus: The taming of the light screw

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.

The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...

Im Focus: Magnetic micro-boats

Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.

The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...

Im Focus: Self-healing coating made of corn starch makes small scratches disappear through heat

Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...

Im Focus: Stellar cartography

The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.

A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...

Im Focus: Heading towards a tsunami of light

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.

"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
