These two kinds are not from the same factory, but the effect is similar. Hewei is made in Thailand, and stomachache is made in Hong Kong. Thailand is the original factory founded by Mr. Li Wanshan, and the formula is the most authentic. The factory in Hong Kong was opened by the youngest son of Mr. Li Wanshan's second room. I took a part of the formula when I separated it, which is very similar, but the technology is not up to the original level in Thailand. You can compare the particles of the two products. The disintegration time made in Hong Kong is too long, the particle shape is different, the process level is poor and the effect is slow. There is no belladonna extract for abdominal pain, so the analgesic effect is slightly worse, just slightly, personally.
