uses of carapa procera seeds

Carapa procera seeds—often known as "crabwood" or "Touloucouna"—are a vital multipurpose resource in West and Central Africa. Primarily valued for their rich oil, they are predominantly used as an active ingredient in traditional medicine, cosmetics, pest control, and soap manufacturing

The seeds are traditionally pressed to extract an oil that provides a variety of practical and medicinal benefits:

1. Traditional Medicine & Skincare

Skin Conditions: The seed oil is celebrated in traditional and ethnopharmacological medicine for treating inflammatory and hyperkeratotic skin conditions, including psoriasis, eczema, scabies, and yaws. It provides soothing, hydrating, and barrier-repairing properties that relieve itching and reduce flaking.

Pain Relief: Topical applications are also used to treat burns, ease body and chest pains, and relieve rheumatism. 

2. Pest Control & Agriculture

Insect Repellent: The oil is highly effective in repelling mosquitoes and other biting insects, serving as a natural, plant-based alternative to synthetic repellents.

Biopesticide: Due to naturally occurring compounds like limonoids, the seed extract is utilized in biological agriculture to control crop-destroying pests—such as the tomato leaf miner (Tuta absoluta)—by acting as an ovicide and larvicide. 

3. Personal Care & Cosmetics

Hair & Scalp Care: The hydrating properties of the oil extend to the hair, where it is used to treat scalp inflammation, dandruff, and ringworm.

Soap & Candles: The fatty acids extracted from the seeds are actively used to make artisanal soaps, candles, and cosmetic emollients. 

4. Food & Nutrition

Edible Oil: While conventionally bitter, the seed oil contains a high ratio of unsaturated fatty acids (around 59%). Research into its nutritional profile has highlighted it as a promising local alternative to conventional cooking oils in food diversification systems.

5. Veterinary Uses

Animal Care: Indigenous communities and farmers use the oil to treat parasites, mange, and various skin ailments on livestock and domestic pets
