As a subject matter expert in chemistry and materials science, I can provide you with an accurate answer to your question.

Gold, in its pure form, is not toxic to humans. It is a heavy metal, but it does not pose the same health risks as other heavy metals such as lead or mercury. Gold is inert, meaning it does not react easily with other substances, which is why it is often used in jewelry and for various medical applications, including implants and some treatments for rheumatoid arthritis.

However, gold can be harmful if it is not in its pure form. For example, gold salts, which are compounds containing gold, can be toxic and have been historically used in medicine in a controlled manner. But these are not the same as the pure gold that is commonly referred to when discussing its safety or use in consumer products.

In summary, pure gold is not considered poisonous, but gold compounds can be toxic.
