What are the morphological characteristics of this plant?
Millingtonia hortensis has large, bipinnate leaves composed of numerous small, oblong leaflets that grow in an opposite arrangement along the stems. The tree typically features a smooth, greyish bark and produces striking, fragrant white flowers that emerge in large, terminal clusters. These blossoms consist of several spreading petals and prominent stamens that attract various pollinators. The plant also develops woody, elongated seed pods that eventually split to release small, winged seeds for wind dispersal. These structural characteristics reflect its adaptation to tropical forest environments.
What is the geographical distribution of this plant?
This plant is native to the tropical regions of South America, specifically spanning across parts of Brazil, Bolivia, and Paraguay. It thrives primarily within the humid environments of the Atlantic Forest and various subtropical lowland ecosystems. Within these habitats, the species prefers moist soils and areas with significant annual rainfall to support its growth. While its natural range is confined to these South American territories, it has been introduced to other tropical climates for ornamental purposes. These cultivated populations are often found in botanical gardens or urban landscapes across similar equatorial zones.
How is this plant cultivated?
This plant, commonly known as the Millingtonia hortensis or Indian Cork Tree, requires full sunlight and well-draining, fertile soil to thrive in tropical or subtropical climates.
It prefers a consistent supply of moisture but must be protected from waterlogged conditions to prevent root rot. During its establishment phase, regular watering is essential to support its rapid growth and large canopy development. Once mature, the tree is relatively hardy and can tolerate moderate drought periods.
Providing adequate space is crucial because its expansive root system and spreading branches need room to expand.
What parts of this plant are used medicinally?
This plant Millingtoniia hortensis utilizes its flowers, bark, and leaves for various medicinal purposes in traditional healing practices. The fragrant flowers are often processed to create extracts used for their calming properties. Additionally, the bark contains bioactive compounds that are frequently employed to treat skin ailments and inflammation. The leaves can also be decocted into a liquid used to address digestive issues or fever. These diverse parts provide a wide range of therapeutic applications for local communities.
According to a study published by "Journal of advanced pharmaceutical technology & research", the aqueous extract of Millingtoniia hortensis L. flowers was evaluated for its effects on hydrogen peroxide-induced senescence in SK-N-SH cells. This flower extract significantly increased cell viability and decreased both apoptotic cells and ROS production in a dose-dependent manner compared to the aging group (P < 0.01). The treatment also reduced the number of SA-β-gal-positive cells (P < 0.01) while promoting the Sirt-1 protein. Additionally, the extract promoted synaptic plasticity by decreasing acetylcholinesterase activity and increasing synaptophysin expression in aging neurons (P < 0.01). These medicinal effects were also revealed by hispidulin, which is the active ingredient in the flower extract.

According to a study published by "Journal of advanced pharmaceuticaal technology & research", the aqueous extract of Millingtonia hortensis L. (MH) from flower was evaluated for its effects on H2O2-induced senescence in SK-N-SH cells. The active ingredient in MH was revealed to be hispidulin, which demonstrated similar effects to the MH extract. MH significantly increased cell viability and decreased both apoptotic cells and ROS production in a dose-dependent manner compared to the aging group (P < 0.01). Additionally, the number of SA-β-gal-positive cells was reduced in MH treatment (P < 0.01) while promoting the Sirt-1 protein. MH also promoted synaptic plasticity by decreasing acetylcholinesterase activity and increasing synaptophysin expression in aging neurons compared to the aging group (P < 0.01).

What side effects this plant can have?
This plant can trigger respiratory complications such as asthma and sinusitis in sensitive individuals. The pollen or airborne particles from the species may act as potent allergens when inhaled. These reactions can lead to inflamed airways and significant congestion in the nasal passages. People with pre-existing pulmonary conditions should exercise caution when near the flowering trees. Such symptoms often worsen during peak blooming seasons when the concentration of particles is highest.
According to a study published by "Asian Pacific journal of cancer prevention : APJCP", Millingtonia hortensis is used for the treatment of asthma, sinusitis, and as a cholagogue and tonic. The aqueous extract of the plant inhibited cell growth and proliferation in an RKO human colon cancer cell line in a dose- and time-dependent manner. Apoptotic cell numbers increased after treatment with the aqueous extract. DNA ladders were clearly observed in RKO cells that were treated with 200, 300, and 400 μg/ml of the aqueous extract for 48 h. These results indicate that the aqueous extract inhibited cell proliferation via the apoptosis pathway.
The main side effects this plant can have are shown in the list below.
