Is Night Blooming Cereus Poisonous?

Night-blooming cereus is a member of the cactus family and comes from Mexico, Central America, and South America. It belongs to the genus Selenicereus, which are known by the common name “moonflower.” The spiky leaves have a unique color pattern that is said to resemble a face.

In order to bloom, night-blooming cereus requires exposure to both 12 hours of darkness (or near darkness) followed by 12 hours of sunlight. Although its flowers are fragrant, they can not troublesome for cats if ingested.

In general, night-blooming cereus is listed as non-toxic to cats, but because plants aren’t part of a cat’s normal diet, ingestion can lead to side effects, which include gastrointestinal irritation, skin irritation, vomiting, and blistering or irritation of the gums and mouth.

The ASPCA recommends that pet owners keep this plant out of their homes if their cat has had an adverse reaction to it in the past.

How Do I Know When My Night Blooming Cereus Will Bloom?

The night-blooming cereus is a tropical plant that blooms as the sun goes down. Its flowers are usually white and fragrant, but they can also be pink or red, depending on the variety.

Their color is most often a pale shade of white, which makes them stand out against the deep blue of the starry sky.

Some of these plants have the ability to bloom only at night, while others can do so both day and night.

The plant that blooms only at night is called the “night-blooming cereus,” while the one that blooms during both day and night is called the “day-blooming cereus.”

To see a Cereus flower at its most beautiful, you must wait until after dark. Night-blooming cereus opens its flowers after dark, usually between 8 and 9 p.m., depending on when dusk falls on that particular night—the later it gets, the longer you’ll have to wait for it to bloom.

At about midnight, buds begin to open slowly, releasing fragrance from the first moment, and are usually fully unfurled about midnight. With dawn’s first light, flowers close again until dusk falls once more—this cycle will repeat every day.


 E. oxypetalum

 has several traditional uses and forms as important ingredients in Malay traditional medicine. The plant is often used to treat bloody phlegm and cough, uterine bleeding, and shortness of breath in old people. In addition, the constituents of

 E. oxypetalum

 are believed to have a strong ability to stifle pain and are capable of neutralizing blood clotting [3]. The stems are reported to cure cardiac affections and dropsy [1]. Vietnamese used the petals of the faded blooms to make soups, which are believed to have tonic and aphrodisiac properties. Additionally, the flowers are used to treat wound abscesses for quick healing.

Antioxidant activity

The aqueous and ethanol extracts of the dried leaves


 were evaluated for antioxidant activity by using hydrogen peroxide scavenging and DPPH assay to determine the free radical scavenging abilities of both the extracts. The results showed the highest percentage of DPPH inhibition (60.37%) in the ethanol extract compared to aqueous extract which showed only 34.23%. The maximum percentage of inhibition in both the methods was observed at 2000µg/ml for the ethanol extract and 500 µg/ml for the aqueous extract respectively.
