The subforum topic statement is a contradiction,
This place is for asking about methods not for opinions of methods ? How you going to get advice on implementing methods if different people don't include their opinion of those methods and how they worked ?
Besides what would the point of even having a discussion be if only people that agreed with the OP posted ? We could simply have one training guide and all sit around and clap and say how great it is.
"Natural" is just another marketing gimmick used to trick people, Same with "All natural" being applied to drugs, supplements, foods, beer, etc etc,, like Natural is some endorsement form God Himself.
Next time you see a add with "all natural " in it. Remember it is a meaningless term. Arsenic is natural, beating something over the head with a club is pretty natural as well.
