The Limerick-based man whose alternative medicine products have drawn a public health warning from the Irish Medicines Board refused to comment yesterday when contacted by The Irish Times.
When contacted by phone, Mr Donie Walsh said he would not issue a statement because the media "would not print the truth, only lies". He would not answer questions.
Earlier, he said he was being "harassed" by the media after this reporter attempted to speak to him on the street. He said he and his family were being "stalked" and he would not comment further.
Yesterday the Mid-Western Health Board said details of a complaint from a Co Clare woman who used the product had been passed on to it by the Garda in recent weeks.
The board also said that in 1998 a complaint was made directly to the board from a Co Donegal-based user of the products.
"We advise people that they use treatment from a registered pharmacist on the advice of a registered medical practitioner," a health board spokeswoman said.
Mr Walsh used an old creamery building at Ardagh as a base to make his products.
The gates leading to the building, which has been refurbished, were locked for most of the day yesterday.
There was also little sign of life at the former main dispensary of Mr Walsh's products in Limerick city. Cherryfield House, on the Ballysimon Road, is listed as Mr Walsh's business address.
The house has a large extension to the rear. Neighbours said Mr Walsh frequents the building regularly, although he is believed now to live in Askeaton, in west Limerick.
