Youhefang is a deceptive scam. It claims to produce and sell a product called "tea pigment", which is said to improve people's health and treat some diseases. However, tea pigment is actually a false concept and does not exist at all.

The basic principle of this scam is to use people's desire for health and longevity to attract them to buy products through publicity and marketing. Youhefang claims that its tea pigment is imported from Japan, which has various functions and can treat many diseases, such as hypertension, heart disease, diabetes and obesity. But these claims have no scientific basis, and tea pigment does not exist at all. A consumer bought this product and found that there was no change in weight and there was no therapeutic effect.

The scam of Youhefang includes the following aspects:

1. False propaganda: Youhefang publicizes that its products can treat many diseases, but there is no scientific basis to prove that the products can really solve these problems.

2. Exaggerated efficacy: Youhefang claims that its tea pigment has many functions, but in fact this ingredient does not exist.

3. High-priced sales: Youhefang is very expensive, and consumers are easily fooled when buying.

So I suggest that you don't believe these marketing propaganda claiming to cure diseases, pay more attention to scientific evidence and choose products carefully. Don't believe those false advertisements. You can know the real efficacy of a product by consulting professional doctors and pharmacists or through authoritative websites.
