I've heard it before. I tried it and applied it for several months, but I only felt that the symptoms didn't continue to develop. Later, I saw on the news that breast health has a good effect on breast lumps, so I ordered a course of trial online. I didn't expect it to soften after just one week, and it almost disappeared after one course of treatment, but I bought a course of treatment to consolidate the effect. You can also try it or go to www.haiji.org to learn about it.
