I have no more information than I have written and posted on this page from phloretina. I read about plant cytotoxic components in clinical trials have provided positive results in hair removal. Specifically LECYTHIS OLLARIA.
Here are the clical trials (are in spanish):
Part 1:
The Hair Removal effect of “COCO de MONO” (Lecythis Ollaria)
Part 2:
The Hair Removal effect of “COCO de MONO” (Lecythis Ollaria)
I read a patent using another cytotoxic component (Ricin) to disable the hair follicles. Which is not toxic spread on the skin, unless it is accompanied by a solvent that will help penetrate the skin, inside the body, that would be lethal.
The patent:
AGENT FOR INHIBITING THE GROWTH OF MAMMALIAN HAIR
If one works Why can not function the rest?
Actually these cytotoxic components cause the death of any cellular process, or simply block it. The problem I see with phloretin is that it would need to use daily to keep the process blocked.
P.D.:
Lecythis Ollaria needs to grow in selenium-rich soils to create the component depilatory cytotoxic properties
SUMMARY (1st part)
In Venezuela the term “coco de mono” (“monkey’s coconut”)is used to designate plants of the genus Lecythis which are characterized by a woody urn -or pot- shaped pericarp covered by an operculum, inside of which the seeds are found.
The family Lecthidaceae is composed of nearly 45 species in tropical South and Central America distributed throughout a vast area running from Brazil to Costa Rica. In the flatlands of Venezuela, where this plant is found, there is a popular belief among the natives of the region that the ingestion of the seeds of this tree causes hair loss from the scalp as well as from the body. According to observations already published, all the individuals who have suffered from intoxication and subsequent hair loss were strangers to the zone and at least in two instances the potential victims were warned of the danger that involved the ingestion of these nuts and the expected consequences in relation to hair loss. Nine cases of intoxication due to the seeds of coco de mono are known, six of them already reported in the medical literature.
In multiple experiments carried out in mice, rats and hamsters “coco de mono” has been administered by mouth at 5 % concentrations and intraperitoneally (aqueous fraction
1:1000 ml. per kg.) in order to study the inhibitory properties of these nuts on hair growth.
A rounded zone of 1.5 cm. in diameter on the dorsal region of the animal was depilated with tweezers thus allowing the pilosebaceus follicles to enter the active growth phase
(anagen) which determined in the control animals a complete repopulation of the depilated area in a 7 day lapse. During the same period, there was observed a complete inhibition of the hair growth in animals subjected to the action of “coco de mono” administered raw as well as in aqueous fraction or purified saline.
After a prolongued exposure to raw coco de mono or active extracts, a variety of histopathological alterations were found in the sacrificed animals, besides the hair growth
inhibition. Among them : atrophy and disappearance of the sebaceous glands, marked atrophy of the epidermis, dema and intraveolar hemorrhage of the lungs, necrotic foci of the
iver and spleen and intense sinusoidal congestion of the adrenals.
The active pharmacological factor turned out to be a hydrosoluble subtance, thermostable, dializable (and therefore of low molecular weight, adsorbable by certain
exchange resins (Dowex 1 and Dowex 50), and finally it was determined that it was the selenium-containing analog of the sulfur amino acid, cystathionine, whose formula is
HOOC-CH (NH2) -CH2 -Se -CH, -CH (NH2) -000H
SUMMARY(2nd part)
Extracts of nuts of “coco de mono” (Lecythis ollaria) were tested for cytotoxic activity, in view of the hair-loss produced by its ingestion in several cases reported in the
medical literature in Venezuela. Mammalian cells growing in vitro were used as the test system, adding a purified crystalline material from extracts of coco de mono, identified as seleno-cystathionine (cystaselenonine), or L-2-amino-4-(L-2-amino-2-car-boxyethly) selenylbutyric acid. Biological activity of this material was exactly equivalent to the aqueous extract used previously, in that the concentration necesary for 50yc inhibition of growth was also 3-5 micrograms per ml. The present studies would seem to indicate that the cytotoxic factor in water extracts of these nuts is entirely due to cystaselenonine. The toxic effects of both crude extracts of nuts as well as highly purified samples of crystalline seleno-cystathionine are
equally reversed by the addition of 1-cystine to the culture medium. Moreover, apparently all of the biological activity in crude water extracts of the nuts seems to be able to be quantitatively accounted for by the amino acid seleno-cystathionine.
Regarding the mechanism of action of seleno-cystathionine, it seems likely that the material interferes with the utilization of the sulfurcontaining amino acid 1-cysteine for protein synthesis. In our cells growing in vitro, this restriction in the amount of utilizable cysteine means that cell growth comes to a halt. However, the hair loss observed after ingestion of nuts of coco de mono is probably not due to a cytotoxic effect of selenocystathionine on the hair follicle cell, so much as to an interference in the utilization of cysteine by the hair folicle cell in the formation of hair. It is well known, of course, that cysteine is present in high concentration in hair, and is of vital importance for the
keratinization process.
