A woman has told a court it was "the biggest regret of her life" not telling authorities about a neighbour's alleged anti-freeze murder plot.
Kate Knight denies attempting to murder her husband
Kate Knight, of Meir, Stoke-on-Trent denies attempting to murder her husband Lee by putting anti-freeze into his red wine which he then drank.
Stafford Crown Court previously heard Mrs Knight, 28, had told neighbour Sarah Johnson about the plan.
Miss Johnson said she regretted not passing the information onto doctors.
Mr Knight, 37, suffered kidney failure, brain damage and is deaf and blind as a result of the alleged incident.
The court previously heard from prosecution lawyers that Mrs Knight had got into debt and wanted to claim her husband's £250,000 life insurance to help.
In a statement read out to the court Miss Johnson, 28, said that after Mr Knight had been admitted to hospital, Mrs Knight told her neighbour that the anti-freeze had not showed up on tests.
'Blocked it out'
The statement said: "She said calmly, 'Yes, it's worked. He has had a biopsy and nothing showed up. If I had not rang the hospital he would have been a goner. Damn'."
When asked in court why she did not tell police or the hospital what she had been told when Mr Knight was taken ill, Miss Johnson said she was "not strong enough" to do so.
She told the jury: "My life at that time was, it was a horrible year. I know it was selfish of me and it's the biggest regret of my life not doing it.
"I just blocked it out and tried to forget about it."
The alleged plot came to light when Miss Johnson told the couple's niece what Mrs Knight had told her and Miss Johnson was subsequently interviewed by police, she said.
The jury also heard how Miss Johnson tasted a sample of the wine and anti-freeze mix Mrs Knight had allegedly prepared for her husband.
Miss Johnson said Mrs Knight had asked her to try it on her behalf.
Miss Johnson told the court: "I always felt a bit overpowered by Kate so I just did a little bit. I don't know why to this day I did."
The trial continues.
