Nandina fruit has been used in traditional medicine for centuries, but its benefits and risks are not as well-known as some other fruits.
Nandina fruit is rich in antioxidants, which can help protect the body against free radicals and oxidative stress.
The fruit is also a good source of vitamins A and C, potassium, and fiber, making it a nutritious addition to a healthy diet.
However, nandina fruit can be toxic if ingested in large quantities, as it contains a compound called nandinine that can cause gastrointestinal symptoms and other health problems.
Potential Risks to Birds
Nandina berries contain cyanide and other alkaloids, which can be toxic to birds.
Cyanide glycosides in the berries can produce highly toxic hydrogen cyanide (HCN), a substance that can cause poisoning.
At least 2000 plant species are known to contain cyanide glycosides, making nandina berries just one of many potential hazards.
The young, rapidly growing portions of the plant and the seeds contain the highest concentration of cyanogenic glycosides.

In the study area, cool, moist growing conditions may have increased cyanogenesis in nandina plants.
Cyanide is generally more concentrated in the seeds and young growth of the plant.
Frost and drought conditions may also increase cyanogenesis in some plant species.
Cedar waxwings, in particular, are known to be susceptible to cyanide poisoning from nandina berries.
In fact, a mass death of waxwings was observed in Georgia and linked to nandina consumption.
It's worth noting that nandina is an invasive species in the southern states, which may contribute to its widespread presence and potential impact on local bird populations.
While it's unlikely to avoid all plants with cyanogenic glycosides, diversifying the food sources in your landscape can help minimize the risk.
Planting multiple species that are preferred by local birds, such as serviceberry, strawberry, and mulberry, can help supplement their diet and reduce reliance on nandina berries.
