Very great, thanks for the sharing 
BTW, to be precise, it is Curing Hemorrhoids
Sutra. I have checked the Chinese spelling and confirmed that it
was refering to Hemmorhoids. The original Chinese website
transliaterated by Mr. Chua Boon Tuan of Rawang Buddhist
Association:
http://www.siddham-sanskrit.com/s-sanskrit2/ChuaBTuan/Sickness-cure.htm
also contains other mantras for curing other illnesses.
Interesting. This is another English translation:
Buddha on Curing Hemorrhoids Sutra
Based on the Chinese translation by
Tripitaka Master Yi Jing of Tang Dynasty
English translation by Yutang Lin
Thus I heard: At one time Bhagavan and five hundred great monks
were in the bamboo grove garden of the great city of Rajagrha. Then
many monks' bodies were inflicted with hemorrhoids; their physical
bodies were thin and weak and entangled in lingering pain and
suffering, and they were extremely worried and annoyed day and
night. Then Meritorious Ananda, having witnessed this matter, went
to where the World Honored One was. He prostrated and touched
Buddha's soles with the top of his head in respect, and then stood
on one side. He said to the World Honored One, "Now in the city of
Rajagrha there are many monks whose bodies are inflicted with
hemorrhoids. Their physical bodies are thin and weak and entangled
in lingering pain and suffering, and they are extremely worried and
annoyed day and night. World Honored One, how to cure all these
hemorrhoid diseases?" Buddha told Ananda, "You may listen to this
Curing Hemorrhoids Sutra, and then maintain its repetition so that
it is well memorized in mind that you would not forget it. In
addition, you should widely proclaim and explain it to others. Thus
all these hemorrhoid diseases would be eradicated, such as wind
hemorrhoids, heat hemorrhoids, depression hemorrhoids, trinity
hemorrhoids, blood hemorrhoids, abdominal hemorrhoids, nasal
hemorrhoids, dental hemorrhoids, tongue hemorrhoids, eye
hemorrhoids, ear hemorrhoids, head hemorrhoids, limb hemorrhoids,
back hemorrhoids, anus hemorrhoids, and hemorrhoids that grow on
joints all over the body, all such hemorrhoid tumors would dry up,
fall off, perish, and undoubtedly be cured. To attain such cure all
should maintain repetition of the following miraculous mantra," and
Buddha uttered the mantra (rendered in Pin Yin):
Da Zhi Ta, E Lan Di, E Lan Mi, Shi Li Pi, Shi Li Shi Li, Mo Jie Shi
Zhi, San Po Ba Du, Sha He.
"Ananda, To the North from here there is a great snow mountain
king, and in it there is a great Sala tree named 'Difficult to
Overcome.' It has three types of flowers: those that are budding,
those in full bloom, and those withered. Just as those flowers fell
as they withered, the hemorrhoids inflicting my monks would fall
like that, no more bleeding and no more pus, forever free from pain
and suffering, and all completely dried up. Furthermore, one who
repeats this Sutra often would attain the wisdom to know one's past
lives and remember events of the latest seven lives, and perfectly
accomplish the mantra practice." Buddha again uttered the following
mantra:
Da Zhi Ta Zhan Mi, Zhan Mi She Zhan Mi, She Mo Ni She Zhan Ni, Sha
He.
As Buddha finished proclamation of this Sutra, Meritorious Ananda
and all in the assembly greatly rejoiced, faithfully received the
teaching and carried on as they were taught.

Not to forget also, the well known Great Compassionate Mantra,
Da Bei Zhou, is known to be able to heal all kinds of illnesses.
Chanting the Medicine Buddha name or Medicine Buddha mantra often
is also advised.
