I have a dataset with a column containing text as follows

```
    Column1
    ----------------------------------------------------------
    dapagliflozin 10 MG / metFORMIN hydrochloride 
    dapagliflozin 5 MG / metFORMIN hydrochloride  
    Fortamet       
    Glucophage      
    Glumetza      
    metFORMIN hydrochloride      
    metFORMIN hydrochloride  / pioglitazone 15 MG     
    metFORMIN hydrochloride  / pioglitazone 30 MG      

```

I am trying to obtain the word count for every unique word, for example, word count for metFormin, word count for hydrochloride, etc. I need help; I tried table function, but it uses the whole row as one word and that's not helpful.
