If u want 2 help someone, and the person don´t want 2 be helped in that way(sab ke apne preferences hote hain, opinions hoti hain ab certain things, including me), then leave it, nothing 2 b offended ab.
And, if ur future plans in case r 2 get into TV, commercials, or beauty tip programmes, then how can u expect everyone 2 follow ur advices? wahaan to is se bhi zeada tankeed hoti hai, both from the viewers and experts side, to tab kya karo ge?
I myself would never use any kind of med or drugs, just coz someone tells me 2 use it, I would consult my doc or any other expert for a diagnose and then go ahead.
And I also happens 2 know that some people infact does react to herbal products as well. For instance, not all herbal products r good for preg. women in that certain time. And not all herbal prod r good for use for people with certain kind of chronic health issues. So, it really should be up to each and every person to consider if an advice is good 4 them. Coz, even one advice can be good for u, may not be as good 4 me.
And if u know of good sites with so much information and knowledge, there is no harm sharing it with others, by just sharing the links.
