Can kudzu powder that's been stored for 10 years still be consumed?

Under normal circumstances, it is not recommended to consume kudzu powder that is 10 years old, as it may have already deteriorated. If kudzu powder is needed, it is advisable to consult a healthcare professional first. The specific reasons are as follows:

Kudzu powder has effects of relieving fever, reducing irritability, promoting body fluid production, and quenching thirst. The shelf life of kudzu powder is typically around two years, although the exact duration may vary depending on storage conditions, packaging methods, and manufacturing date. If the kudzu powder has been stored for 10 years, it is highly likely to be expired and may exhibit clumping, discoloration, or mold growth; therefore, consumption is generally not recommended.

The nutritional components in kudzu powder gradually break down and diminish over time, reducing its nutritional value. Expired kudzu powder may harbor harmful bacteria, and ingestion could irritate the gastrointestinal mucosa, leading to discomfort such as bloating and abdominal pain, potentially causing unnecessary harm to the body.

It is recommended to store kudzu powder in a cool, dry place, away from direct sunlight and moisture. Additionally, ensure the packaging is well sealed to prevent exposure to air and humidity, which can help extend its shelf life to some extent.
