Job's Tears

Meet Job's Tears (*Coix lacryma-jobi*), a humble yet powerful grain that has been a staple in Traditional Chinese Medicine (TCM) and Asian cuisine for centuries. Often called 'Pearl Barley' (though botanically distinct from true barley), this tear-shaped seed is a nutritional powerhouse. It's not a chemical supplement but a whole food that acts as a gentle diuretic, anti-inflammatory agent, and immune booster. Known as 'Yi Yi Ren' in TCM, it helps the body remove excess moisture and toxins. Think of it as nature's way to help you 'de-puff', detox, and energize naturally.

Beyond fluid balance, the seeds contain unique antioxidants that modulate the immune system, making the body more resilient to seasonal threats. For skin health, internal consumption has been linked to reduced acne and eczema flare-ups due to its cooling and detoxifying properties.
