Plumula Nelumbinis, also known as Lian Zi Xin or lotus plumule, is the green embryo found inside the seed of the sacred lotus (Nelumbo nucifera). In Traditional Medicine, it is revered for its ability to clear heart fire, calm the spirit, and regulate internal heat. Bitter in taste and cooling in nature, this herbal ingredient is often used in small quantities within calming, cooling, or hemostatic formulas.
Modern pharmacological research confirms its traditional uses, highlighting its neuroprotective, cardiovascular, and antioxidant properties. Rich in alkaloids such as neferine and liensinine, Plumula Nelumbinis shows promise in managing insomnia, anxiety, inflammation, and metabolic disorders.

5 Key Health Benefits of Plumula Nelumbinis
1. Cardiovascular Protection

Neferine and its related alkaloids have demonstrated antihypertensive and anti-arrhythmic properties. They help reduce heart rate, improve cardiac output, and protect the vascular endothelium (Chen et al., 2020).
2. Neurological and Sleep Support

Traditionally used to “calm the heart and spirit,” modern research shows that Plumula Nelumbinis reduces anxiety, promotes relaxation, and improves sleep quality through GABAergic modulation (Xiao et al., 2022).
3. Antioxidant Effects

The herb’s flavonoids and alkaloids scavenge free radicals and reduce oxidative stress, protecting cells and tissues from age-related damage (Huang et al., 2023).
4. Anti-inflammatory Activity
Extracts of Plumula Nelumbinis suppress inflammatory cytokines, aiding in the management of chronic inflammation and autoimmune-related conditions.
5. Blood Sugar and Lipid Regulation
Emerging evidence suggests that lotus alkaloids may help regulate blood glucose and improve lipid metabolism, supporting overall metabolic health.
