What are the morphological characteristics of this plant?
Nymphaea lotus has large, circular, floating leaves that can reach up to 30 centimeters in diameter, featuring a deep notch where the petiole attaches. These leaves are typically bright green with a smooth, waxy surface that helps repel water. The plant produces showy, solitary flowers that rise slightly above the water level on long, sturdy stalks. These blossoms consist of numerous white petals arranged in multiple layers around a central cluster of yellow stamens. Below the surface, a thick, tuberous rhizome anchors the plant firmly into the muddy substrate of its aquatic habitat.
What is the geographical distribution of this plant?
This plant is native to the tropical and subtropical regions of Africa, ranging from Egypt and Sudan in the north down to South Africa. It is commonly found in slow-moving or stagnant freshwater habitats such as marshes, swamps, and the edges of lakes. The species thrives in various climates throughout the Nile River basin and across much of the African continent. Its distribution is closely tied to the availability of shallow, warm water environments. Many populations also extend into parts of the Arabian Peninsula where suitable aquatic conditions exist.
How is this plant cultivated?
This plant Nymphaea lotus requires full sunlight and warm water temperatures between 70 and 85 degrees Fahrenheit to thrive in a deep aquatic environment.

What are the herbal preparations of this plant?
This plant is Nymphaea lotus, a species used to create medicinal aqueous extracts, decoctions, and ethanolic extracts for various therapeutic applications. An aqueous extract is often prepared by soaking the plant parts in water to pull out water-soluble compounds. A decoction involves boiling the plant material in water to ensure the extraction of more resilient chemical constituents. Ethanolic extracts are produced using alcohol to target specific non-polar bioactive molecules within the plant. These different preparation methods allow practitioners to tailor the concentration and type of medicinal properties being utilized.
According to a study published by "Heliyon", Nymphaea lotus is known for several medicinal properties, including its protective role against tissue damages. The aqueous extract of Nymphaea lotus contains bioactive compounds of pharmacological importance such as pyrogallol, oxacyclohexadecan-2-one, 22-Desoxycarpesterol, 7,22-Ergostadienol, β-sitosterol and Dihydro-β-agarofuran. This plant possesses phytochemicals capable of reducing gold salts to nanoparticle form, resulting in spherically-synthesized NL-AuNPs measuring 25-30 nm. In studies involving 30 rats, doses of 5 mg/kg NL-AuNPs were found to be more potent against kidney damage induced by cadmium, whereas high doses of ≥10 mg/kg NL-AuNPs could be suggested toxic. Consequently, doses of Nymphaea lotus-derived nanoparticles up to 5 mg/kg could be considered safe for the treatment of renal damage occasioned by cadmium.
The main herbal preparations of this plant are shown in the list below.

What side effects this plant can have?
This plant can cause significant reproductive damage including the development of aberrant sperm cells, chromosomal aberrations, and germ cell mutations. These genetic disruptions pose serious risks to long-term fertility and hereditary stability. Beyond reproductive harm, exposure to the plant is linked to concerning liver alterations that may impair metabolic function. Additionally, the consumption of this species is known to produce various psychoactive effects on the central nervous system. Such diverse physiological impacts highlight the inherent toxicity of the species.
According to a study published by "Interdisciplinary toxicology", the aqueous and hydro-methanol extracts of Nymphaea lotus L. were evaluated for genotoxicity and antigenotoxicity using Swiss albino mice. To assess acute toxicity, the highest attainable dose of 5 000 mg/kg was administered to five groups of mice with n=4/group. While the 5 000 mg/kg concentration did not induce acute toxicity, both the aqueous and hydro-methanol extracts of N. lotus increased the frequency of aberrant sperm cells. Mice in the genotoxicity and antigenotoxicity groups received 0.2 mL of extract per day for 10 days. These results demonstrated the potential of the extracts to induce somatic and germ cell mutation in male mice. Despite this, the extracts were also able to ameliorate the genotoxic effect of 60 mg/kg of methyl methane sulfonates (MMS) in bone marrow cells.
The main side effects this plant can have are shown in the list below.
- aberrant sperm cells
- chromosomal aberrations
- germ cell mutation
- liver alterations
