Nymphaea nouchali, commonly known as blue lotus or star lotus, is used in traditional medicine systems of South and Southeast Asia. Ethnomedical sources and Ayurvedic texts sometimes mention its use for conditions that could include dizziness, such as general malaise, nervous disorders, or as a calming agent. However, the references are often vague, and direct attribution to the treatment of dizziness (vertigo, lightheadedness) is not strongly documented. The traditional rationale may stem from its reputed sedative, anxiolytic, or adaptogenic properties, which could, in theory, help with symptoms associated with dizziness due to stress or anxiety.

Scientifically, there is a lack of robust clinical data supporting the use of Nymphaea nouchali for dizziness specifically. While some phytochemical studies have identified alkaloids, flavonoids, and glycosides with possible neuroactive or circulatory effects, no controlled trials or pharmacological studies directly demonstrate efficacy for dizziness. Thus, its use for this condition is based primarily on traditional or anecdotal reports rather than validated scientific evidence.
