What exactly is Melaleuca?

[elizabeth]

Some people I know "advertise" for Melaleuca. What does this mean? How does it work? They say they are not MLM and that they don't sell products but I don't really believe that. they also say that they own their own business and don't work "for" Melaleuca. But they do host parties and such, and want people to join Melaleuca.

They post all over Facebook in different groups looking for people to join their team - but the messages seem vague to me, and if I didn't know them I'd think it was spam.

The messages go something like this: "We work with a team of motivated people - mostly women - who are passionate about health and wellness. Our sole source of revenue now comes from our partnership with a US-based wellness company. This has allowed us to build our dream home. Let us know if you are interested in joining our motivated team."

Please help me...I can't seem to find any information on the web about what Melaleuca really is, and what my friends do, and how it works. Is it a scam?
