A mother allegedly poisoned her nine-year-old daughter by putting urine in her intravenous drip while she was receiving treatment in hospital for a potentially fatal condition.

The woman appeared in a Hunter Region local court on Wednesday over charges including using poison to endanger life or inflict grievous bodily harm and assault causing actual bodily harm.

Police charge sheets tendered to the court detailed the allegations, including that the mother administered her daughter with 'noxious' urine using a catheter inserted in the girl's jugular vein on March 11, The Daily Telegraph reported.

Detectives from the NSW Police Child Abuse Squad at Newcastle in the Hunter Valley established Strike Force Twine in March this year to investigate the alleged abuse of the girl who had been admitted to Westmead Children's Hospital with a life-threatening condition.

The woman was arrested in the Hunter region in July and charged with alleged intravenous and by-mouth poisoning of the nine-year-old, who suffers from a rare disease.

Police also allege the girl was given tablets last year which worsened her medical condition.

Detectives alleged the girl suffered 'serious life threatening infections never seen before by treating doctors' in a police bail determination.

The girl has since been released from hospital and is recovering.

On Wednesday, the court heard an apprehended violence order barring the mother from contacting her daughter would be continued.

The matter was adjourned, to be heard in Newcastle District Court on October 14.

The woman had posted about her daughter's medical problems on Twitter and written about her treatment on online forums.

Outside court her solicitor Michael Nott told the Telegraph 'these charges will be vigorously defended'.
