1. Fake experts: Some fraudsters with independent life sciences claim to be authoritative experts, but in fact they may not have relevant scientific or medical certifications. They call themselves "imperial doctors" or "health experts" and make a profit by selling their own products.

2. Selling fake products: Some independent life science companies claim that their products can treat various diseases, but there is no scientific basis in fact. These therapies include traditional herbs, decoction, aromatherapy or other natural therapy products.

3. Marketing strategy: Some independent life science companies adopt high-pressure marketing strategy to promote products to consumers. They will say that you need to buy a lot of products to achieve the best results, or let you attend paid seminars or courses to get further help.

4. No scientific basis: Some independent life science companies claim that the treatment plan lacks scientific basis, or has not been widely tested and proved to be an effective method to treat diseases.

5. Marketing for specific groups: Some independent life science companies will market for specific groups, such as the elderly, patients with cancer or other serious diseases, to defraud their money with their needs and fragile psychological state. It should be noted that these scams are only part of it. Consumers should be cautious when choosing independent life science products or treatment programs to ensure that the products and programs they buy have sufficient scientific basis.
