Singer-songwriter Joni Mitchell is "getting stronger each day" after being taken to hospital earlier this week, a statement published on her website says.
The 71-year-old winner of eight Grammys, was found unconscious in her Los Angeles home on Tuesday afternoon.
A statement released on her website late on Friday said the singer was "resting comfortably".
It is still not clear what Joni Mitchell is being treated for.
"We are encouraged by her progress and she continues to improve and get stronger each day," the statement said.
In December, Canadian-born Joni Mitchell told Billboard magazine that she had a rare skin condition, Morgellons disease, which prevented her from performing.
"I can't sing any more - don't miss it. I can't play any more - don't miss it. I've got all these instruments laying around and hopefully one day I'll pick them up," she was quoted as saying.
Morgellons is a controversial condition and is not recognised by mainstream medical authorities.
Sufferers say it is characterised by crawling and stinging sensations under the skin but many in the medical community believe it is a psychiatric disorder.
The legend behind
Joni Mitchell describes herself as a "painter who writes songs" with a "little helium voice".
She only started singing in the mid-60s "for smoking money," she once told US radio station NPR.
But her richly detailed, confessional lyrics changed folk music.
Before Mitchell, singer-songwriters concentrated on love and politics. After her, they sang about themselves - their fears, their pain, and how the loss of a lover can leave you feeling: "The bed's too big, the frying pan's too wide."
Her reputation as a fragile, confessional lyricist does her a disservice. Mitchell's writing may be unflinchingly personal, but it is also rich with imagery and engaged with the world beyond her "yellow curtains".
"My work has always contained the question of how far the pop song could go. What themes it could hold without collapsing," she once said.
Her most famous compositions are the poem-songs she released during her early, Laurel Canyon years, but she was incorporating jazz and world music in her work long before it became fashionable.
"My music is not designed to grab instantly," she once said. "It's designed to wear for a lifetime, to hold up like a fine cloth."
It would be impossible to select a definitive list of her best songs, but here is a quick guide to seven of the most popular ones.
Her famous songs include- River, Woodstock, A Case of You, Free Man in Paris, Big Yellow Taxi, Help Me, Both Sides Now. ?BBC
