A friend of ours was bitten by an unknown spider about two weeks ago. The doctor gave him 1000mg Amoxipen. The bite site has apparently formed a hole in the skin or become hollow (die byt plek het 'n gat ingeval) and he seems to be very sick, so much so that he spends a lot of time lying down.

Does anyone have any advice on any further treatment for such a bite? Perhaps some home remedies (boereraad)?
