Bamboo salt

Someone told me bamboo salt can help to cure sickness that due to high intake of acidic food. According to the catalog and information given by that person, sodium chloride is acidic and sodium is acidic. As a chemist, we all know that sodium chloride is neutral and sodium is an alkaline metal. They even use methyl orange to prove that sodium chloride is acidic and bamboo salt is basic. They have testing report from Singhealth to support their product is good for health. In fact, the testing report only shows that there is no heavy metal (Mercury, Lead, and etc.) in the bamboo salt. They said that table salt is a high sodium salt which is bad for human health. The question is, how to have high sodium salt? The amount of sodium ion is higher than amount of chloride ion? We all know that one sodium ion combine with one chloride ion will give one sodium chloride compound. So, how to have high sodium salt? And, one mole of sodium hydroxide (Basic) react with one mole of hydrochloric acid will produce one mole of sodium chloride and one mole of water. Sodium chloride is neutral. I am thinking that for those who do not have chemistry knowledge, after approached by direct sales of bamboo salt will believe that sodium chloride is acidic and sodium is acidic. This is misleading.
