le cucurbitacee come la zucca le zucchine i cetrioli i meloni i cocomeri 
le angurie, se hanno sapore amaro possono contenere tossine che fanno 
cadere i capelli

ecco dove vanno a finire i miliardi di finanziamenti di Telethon per la 
ricerca sul cancro: se li intascano i soliti..., e ai malati di cancro 
fanno bere beveroni di succo di zucchine amare che gli fanno cadere i 
capelli, e la pelata è la prova che sono stati sottoposti a chemioterapia

 ricerca sul cancro:
 
Io vorrei sapere dove vanno i cetrioli e le zucchine...

e le carote... :-(

Più tardi leggerò il full text, ma l'abstract di quell'articolo di Jama:
 
   Hair loss induced by plant ingestion, a classic cause of toxic anagen 
effluvium, is rare. The most commonly involved plants are colchicum, 
tubers of Gloriosa superba, Lecythis ollaria, and Leucaena leucocephala 
(containing mimosine).1 The implicated mechanism of toxic effects from 
these plants on the hair follicle seems mainly due to their antimitotic 
action.
 
parla di piante la cui tossicità è dovuta a colchicina, selenio o 
mimosina, quindi informiamoci su di esse:
 
Colchicum = noto genere di piante dai bei fiori ma tutte molto tossiche 
(contengono colchicina):
 
https://en.wikipedia.org/wiki/Colchicum_autumnale#Toxicity
 
 
   Colchicum plants are deadly poisonous due to their colchicine 
content, and have been mistaken by foragers for ramsons, which they 
vaguely resemble.[11] The symptoms of colchicine poisoning resemble 
those of arsenic, and no antidote is known. This plant poses a 
particular threat to cats due to its colchicine and alkaloid content. 
The leaves and fruit of meadow saffron contain the highest level of 
toxins,[clarification needed] but all parts of the plant are regarded as 
poisonous.[12]
 
Gloriosa superba = "flame lily" o "tiger claw", pianta tropicale molto 
velenosa per uomini e animali:
 
https://en.wikipedia.org/wiki/Gloriosa_superba#Toxicity
 
 
   This plant is poisonous, toxic enough to cause human and animal 
fatalities if ingested. It has been used to commit murder, to achieve 
suicide,[9] and to kill animals.[5] Every part of the plant is 
poisonous, especially the tuberous rhizomes. As with other members of 
the Colchicaceae, this plant contains high levels of colchicine, a toxic 
alkaloid. It also contains the alkaloid gloriocine. Within a few hours 
of the ingestion of a toxic amount of plant material, a victim may 
experience nausea, vomiting, numbness, and tingling around the mouth, 
burning in the throat, abdominal pain, and bloody diarrhea, which leads 
to dehydration.[10] As the toxic syndrome progresses, rhabdomyolysis, 
ileus,[9] respiratory depression, hypotension, coagulopathy, haematuria, 
altered mental status, seizures, coma, and ascending polyneuropathy may 
occur.[10] Longer-term effects include peeling of the skin and prolonged 
vaginal bleeding in women.[9] Colchicine is known to cause alopecia. One 
case report described a patient who accidentally ate the tubers and then 
experienced hair loss over her entire body, including complete 
baldness.[11] Poisonings can occur when the tubers are mistaken for 
sweet potatoes[9] or yams and eaten.[11] The plant can be dangerous for 
cats, dogs, horses,[12] and livestock,[13] as well.
 
Lecythis ollaria = "coco de mono", pianta amazzonica che diventa 
velenosa quando accumula troppo selenio:
 
https://en.wikipedia.org/wiki/Lecythis_ollaria#Toxicity
 
 
   The nuts have a pleasant flavour and are eaten by humans.[2] When two 
previously healthy women in South America developed unexplained nausea, 
vomiting and neurological symptoms, followed two weeks later by heavy 
hair loss, no cause could at first be found. It was later established 
that they were suffering from acute selenium toxicity brought on by 
eating paradise nuts. They still had elevated levels of selenium in 
their blood eight weeks after they had eaten the nuts.[3] Further 
investigation of the tree found that the tissues of the bark, leaves, 
capsules and seeds all contained selenium but that the highest 
concentration was in the nuts which contained about five grams per 
kilogram, about half of which was soluble in water.[4] The tree is 
considered to be a selenium accumulator and part of the element is bound 
to very selenium-rich proteins.[5]
 
Leucaena leucocephala = mimosacea i cui semi sono tossici per i non 
ruminanti:
 
https://en.wikipedia.org/wiki/Leucaena_leucocephala#Other_limitations
 
 
   The seeds contain mimosine, an amino acid known to be toxic to 
nonruminant vertebrates.[9]
 
Notare che nessuna di quelle piante sono le nostre zucche, zucchine, 
cetrioli, meloni, cocomeri e angurie, tutte cucurbitacee. Tanto più che 
Colchicum e Gloriosa non sono cucurbitacee, ma appartengono alla 
famiglia delle liliacee, e neanche le altre due specie velenose citate 
sono cucurbitacee. Possibile che anche nelle cucurbitacee possano 
esserci sostanze tossiche? O la zuppa è stata fatta scambiando qualche 
ingrediente con piante velenose? Beh, più tardi leggerò il full text.
