Hi. Pl start doing warm water gargles. Pl. mix little pure turmeric powder in the glass of warm water and gargle twice a day for one to two weeks. If you can get Sitopaladi choorna of good quality from India, it will return your good voice. In Ayurveda classics its mentioned to turn the voice a cuckoo s voice if used as per directions. However its little exaggeration in today s world conditions. It s a herbal combo powder and is to be licked with honey for four weeks or so. It strengthens larynx, cleans upper respiratory tract. Vyoshadi vati (Ayurveda lozenges) are also indicated to be sucked for fighting hoarseness of voice. These are harmless medicines. May get through online orders too. If you have any further query please consult through direct question. Hope it helps.
