Aloe today, part five

...at present however, these compounds are gradually losing the interest of gastro-intestinal phytotherapeutic research because they have been replaced by compounds with a blander action (such as the so-called “mechanical” laxat ives”, that is of swelling, such as psyllium) point ing out , however, new horizons in the antitumour field (apoptosis of carcinogenic cells) of future development...

Aloe today, part four

Aloe and its constituents/derivatives is considered the most energetic laxative of the common purgative drugs (senna, cascara, frangula, rhubarb) and, as such, was greatly used in the past from time immemorial (the Ebers Papyrus from Thebes). Even today, in the presence of serious constiption and in individual, non-continuous cases, it can be used profitably...

Aloe today, part three

As already recalled in Par t One (Natural 1, September 2002), Pharmacopoeias do not refer to a drug consisting of aloe leaf but of its dried latex (see Par t Two, point 2.1 in Natural 1, October 2002). In this regard, the American Pharmacopoeia (USP 25, p. ) states: “Aloe is the dr ied juice of the leaves of Aloe barbadensis Miller, commercially known as aloe Curaçao, or Aloe ferox Miller and its hybr ids with Aloe africana Miller and Aloe spicata Baker, commercially known as Cape aloe …

Aloe today, part two

The various species of aloe (see Par t One in Natural 1, September 2002) are the source of two important groups of compounds used in therapy: anthranoids [aloe latex] and polysaccharides (aloe gel) ; both groups are contained in the leaf and this may cause some discr iminatory difficulties, aggravated by the easy, reciprocal and inevitable contamination during extraction...

Aloe today, part one

he Aloe genus, known and used in phytotherapy for thousands of years, continues to be of therapeutic interest from new points of view as well: in addition to its recognised laxative and disinfectant qualities, its immunostimulant, antiulcerogenous and ant i-tumoural characteristics mak e it worthy of closer study. Despite some terminological difficulties of a botanical and chemical nature, which hinder the identification of the drug and its derivatives, all the species of the genus seem to contain, with the natural variants, active ingredients of a similar chemical structure, which are divided into the two chemical groups of anthranoids and polysaccharides. Botanical, chemical and phytotherapeutic
research continues and, as far as possible, will be described here below for the purpose of facilitating its comprehension and topicality...

A well lubrificated machine

Although apparently solid, 60-70% of the human body is actually made up fluids. The task of the lymphatic system is precisely that of allowing a balanced flow of the fluids to the various compartment s of the organism and preventing their stasis...
