Lathyrus sativa for Toxoplasmosis

I've been told that Lathyrus sativa is suitable for treating my 18 month old cat who is fighting Toxoplasmosis; high titres for FIP; and the after effects of feline influenza.

I can't find any reference to what type of personality and what symptoms this remedy would prove most useful to.

My cat is very affectionate with humans she trusts; she is bright, less patient or tolerant in general terms than many cats; enjoys time on her own and roams large distances but also loves her feline companions and has learned to tolerate dogs. She is being good about her confinement but I feel
she is bored despite not having the energy to do much.

Could someone comment if this is the optimal remedy for this, or are there other suggestions?
