Shri raju,
I used to be a very active member in this forum in the past, but now, due to old age and weaknesses, I do not use the PC very much and so my visits to TBF have become occasional.
As an old man of 74 may I tell that learning mantras, etc., that too sanskrit mantras, through the medium of QUERTY key-pad and so on, will, at best, be a half-hearted endeavour. There is a popular saying among us Kerala Brahmins that if one learns through such medium, the word "Muhoortham" (मुहूर्त्तं in Sanskrit) may finally be learnt as "Moothram"!
The Sloka which you refer to is the Dhyaana Sloka for Dhanvanthari (and not Dhanvanthiri). The correct version of this Sloka (there could be more than one Dhyaana Sloka and we may not come to know of all of those.) is as given below in Devanaagari script, IAST form and Malayalam fonts (in case this helps you) : —
शंखं चक्रं जलौघं दधत् अमृतघटं चारु दॊर्भिश्चतुर्भिः ।
सूक्ष्मस्वच्छातिहृद्यांशुक परिविलसन् मौलिं अम्भॊजनॆत्रम् ॥
कालांभॊदॊज्ज्वलांगं कटितटविलसच्चारु पीतांबराढ्यम् ।
वन्दॆ धन्वन्तरिं तं निखिलगदवन प्रौढ दावाग्निलीलम् ॥
śaṃkhaṃ cakraṃ jalaughaṃ dadhat amṛtaghaṭaṃ cāru dorbhiścaturbhiḥ |
sūkṣmasvacchātihṛdyāṃśuka parivilasan mauliṃ ambhojanetram ||
kālāṃbhodojjvalāṃgaṃ kaṭitaṭavilasaccāru pītāṃbarāḍhyam |
vande dhanvantariṃ taṃ nikhilagadavana prauḍha dāvāgnilīlam ||
ശംഖം ചക്രം ജലൗഘം ദധത് അമൃതഘടം ചാരു ദോര്ഭിശ്ചതുര്ഭിഃ |
സൂക്ഷ്മസ്വച്ഛാതിഹൃദ്യാംശുക പരിവിലസന് മൗലിം അംഭോജനേത്രം ||
കാലാംഭോദോജ്ജ്വലാംഗം കടിതടവിലസച്ചാരു പീതാംബരാഢ്യം |
വന്ദേ ധന്വന്തരിം തം നിഖിലഗദവന പ്രൗഢ ദാവാഗ്നിലീലം ||
The Dhanvantari mantra is of two types; for doing homams etc., it should end with the word "svaahaa" whereas for japam the end word is "namah".
The mantras given in post #13 are also misleading in the sense of their pronunciation being unclear.
Last, but not least, chronic diseases may not be cured by merely chanting Dhanvantareemantra and giving one "Uddharani" full of water; it will be more advisable to consult a competent doctor and follow his/her advice. The mantra-water cure can be tried as an additional exercise.
