Teena Marie Dead
We're told officials searched Teena's home in Pasadena , CA -- but only found some herbal medication -- and we're not talking marijuana.

We're told an autopsy and toxicology tests will be performed on her body later this week -- but so far, officials are leaning towards the theory that she died of natural causes.

As we previously reported, Teena -- once considered Rick James' protégée -- suffered a grand mal seizure just one month ago.
