Excoecaria agallocha is a species of mangrove tree that is native to tropical and subtropical regions of the world, including India, Southeast Asia, and parts of Africa and Australia. It is known for its milky sap, which can cause irritation to the eyes and skin, hence the common name blind-your-eye mangrove or milky mangrove and "Thela" in Maldives.
The tree can reach heights of up
to 30 feet and has glossy, dark green leaves. It is often found in brackish
water or along riverbanks, in the estuarine and coastal regions of the tropical
and subtropical areas. The tree is typically found in the intertidal zone of
mangrove swamps, and can also be found in freshwater swamps. The tree is also
known for its ability to grow in saline soils and can tolerate saltwater
inundation.
The tree has many medicinal uses
in some cultures. The leaves, bark, and roots are used to treat various
ailments, including diarrhea, fever, and skin diseases. The sap has been
traditionally used to treat wounds and has been used as a fish poison.
However, the sap of this tree is
toxic and should be handled with care. If ingested, it can cause severe
vomiting, diarrhea, and even death. In case of skin contact, it can cause
severe dermatitis, blistering and even blindness, if it comes in contact with
eyes.
The hard wood of Excoecaria agallocha is highly valued for its strong, sweet
scent and is often used as incense in religious and spiritual rituals. The wood
is also believed to have purifying properties and is used to cleanse and
sanctify sacred spaces.
In some cultures, the wood is used
in combination with other fragrant woods and mineral stones to create a unique
and complex aroma. It is believed that the combination of different fragrances
creates a spiritual atmosphere and enhances the effectiveness of the ritual.
The wood can be used in various
forms, such as chips, sticks, or powder, and is usually burned on charcoal or
in a special burner. It is also used to make traditional incense sticks, which
are sold in many markets.
The hardwood of the tree is also
used for other purposes such as furniture making, construction and carving. The
tree is also known for its ability to grow in saline soils, which makes it a
valuable resource for reforestation and coastal protection.
