'Braxton Family Values' Star -- Released from Hospital

Toni Braxton's brother-in-law -- who also stars on "Braxton Family Values" -- has been released from the hospital after suffering a blood clot in his lungs ... TMZ has learned.

Vince Herbert was rushed to a NY hospital two weeks ago ... and the whole Braxton fam rallied around the music producer for support ... even canceling important media events.

Sources close to the family tell TMZ Toni is extremely relieved ... but she considers the situation a "wake-up call" to get her own health checked out more regularly ... especially because she suffers from lupus.
