Cassia obovata has several medicinal benefits, primarily related to hair and scalp health, such as acting as a conditioner, strengthening hair, and helping with dandruff due to its antifungal and anti-inflammatory properties. It also has internal uses, including mild laxative effects, antioxidant support, and potential benefits for blood sugar control and liver health, though some of these require more human research. 

Hair and scalp benefits

Hair conditioning: It leaves hair feeling softer, shinier, and more voluminous.

Strengthening: Cassia coats each hair strand, which helps strengthen it and reduce breakage, especially in chemically treated hair.

Scalp health: It has antifungal properties that can help with dandruff and itchiness caused by fungi like Malassezia furfur.

Mild hair tinting: It can give light brown to blonde hair subtle golden or yellowish highlights without the intense color of henna.

Reduced inflammation: Its anti-inflammatory properties may help soothe scalp inflammation. 

Internal and other benefits

Digestive health: It has a mild laxative effect and can help with occasional constipation.

Antioxidant support: It contains antioxidants that help fight free radicals and support skin health.

Liver support: Animal studies suggest it may have a protective effect on the liver.

Blood sugar regulation: Emerging evidence suggests a possible hypoglycemic effect, but more human studies are needed.

Antibacterial potential: Extracts show modest antibacterial activity against certain bacteria.
