Diamond Flower is a little herb with white blooms from the family Rubiaceae. It is widely found in Kerala by the name Parpataka Pullu. Its botanical name is Oldenlandia corymbosa.
Since it often grows along with other grasses and due to its small size, you might easily overlook it. However, this medicinal plant is used in certain traditional systems for treating Fever [ref1].
Note: some people also consider Fumaria indica as Parpataka.
The leaves of Diamond Flower are elongated with pointed tips. They are usually 1.5 cm long at most. They grow around the stem with up to 8 leaves from each node. Sometimes it can be fewer than that.
The white flowers grow from leaf axils. They have a light blue tinge and usually occur in groups of two or three. Each flower has four petals, which might be the reason behind its common name – Diamond flower. It is barely three millimeters in width.
The fruits are also green with lots of seeds inside them. The plant grows to a height of about 10 to 20 cm. It has lots of small branches and sub-branches, all looking light green.
In Ayurveda, Parpatah (Sanskrit name) has various medicinal uses. There are several species known by the same name as all of them possess the ability to cure the same illness. However, a majority consider Diamond Flower (Oldenlandia corymbosa) as Parpatah.
