Can you still eat Houttuynia cordata (fishy-smelling herb) if it gets moldy?

Generally speaking, Houttuynia cordata (fishy-smelling grass) that has molded should not be consumed. The detailed explanation is as follows:

Molded Houttuynia cordata has already been contaminated by fungi, which can produce harmful substances such as aflatoxins. These substances are toxic and may cause harm to the body if ingested. Even if only partially molded, invisible mold may have already spread throughout the entire plant. Continued consumption poses health risks and may lead to gastrointestinal discomfort such as vomiting and diarrhea. Long-term intake may also affect liver and kidney function.

Regardless of the extent of mold, Houttuynia cordata should not be consumed any further. Mold growth is an obvious sign of food spoilage; at this point, its nutritional components have already been destroyed, and its taste and flavor have changed. Consuming it will not provide nutrition but will instead endanger health.

When storing Houttuynia cordata daily, it is important to keep it dry and well-ventilated to avoid moisture and mold. Once mold is detected, it should be discarded immediately. Do not consume it with the hope of being lucky, in order to ensure food safety.
