I have been buying "Brown Lu" on Amazon before. The ginseng has a long-lasting traditional Chinese medicine taste and I like to use it. But what I received today is "Black Lu", the packaging cover is a little different from before, and the smell of Chinese medicine disappeared quickly when shampooing, and there was some other light scent when I smelled it. I don’t know if there are two effects. There are differences in taste, so just use it.
