Drinking rainwater

Q: According to a Hadith, rainwater is shifa for all diseases. Does this also apply to drinking rainwater which has been taken out from the ground? Because when it rains, the rainwater passes through rocks and is stored underground and taken out through machines for drinking. So is it necessary to collect and drink the rainwater before it falls to the ground or will the underground water also have the same benefits for Shifa?
