Coma boy Archie Battersbee has given his mum “a glimmer of hope” as she begs judges not to removed his life support.
Hollie Dance, 46, said Archie, 12, had responded to music and smell.
She said: “His blood pressure went up, so we put on a deep-breathing meditation recording and put lavender oil under his nose and within 10 minutes his blood pressure dropped to normal levels.
“It’s a glimmer of hope. He’s in there and he’s going to wake up, he just needs time.”
Doctors at the Royal London Hospital in Whitechapel argue that Archie is “brain-stem dead” and last week won a High Court bid to remove his life support.
Today Archie’s family will mount an appeal to challenge the ruling.
Hollie said: “All I want is for them to give him time to heal.”
Archie has been in a coma since he was found unconscious after trying a social media blackout dare at his home in Southend, Essex, on April 7.
