For centuries, people in India used neem oil to treat and prevent various skin diseases. The oil is extracted from the fruits or leaves of the widely grown neem plants in that country. The name oil is now available through the world, but you can still make it individually from the fruits or leaves.
1. Extraction from Neem Fruit
To extract neem oil from the fruit, you will not need any mechanical or modern equipment. You can do the entire procedures manually and traditionally. You will need about 2 pounds of neem fruits and seeds, a sieve, a rolling pin, a bucket, a cloth bag, and 5 cups of water.
First, place some handfuls of neem fruits and seeds on a table and crush them by using a rolling pin. Put away the crushed produce and place them inside the cloth bag. Keep doing this with all the remaining fruits and seeds. When all the fruits are crushed and put inside the cloth bag, place the bag in a bucket. Now you need to pour 5 cups of water over the cloth bag in the bucket. Remove the bag from the bucket and pour out the water. Place a sieve inside the bucket and put the cloth bag on top of the sieve.
The water actually helps the push out the oil from neem fruits and seeds. Now that you place the bag on top of a sieve, the oil will drop into the bucket naturally. You may need to wait overnight to get a reasonable amount of neem oil. The oil that comes out from the fruits and seeds will be clean, meaning it will not contain pulp from the crushed produce.
2. Extraction from Neem Leaves
Extracting neem oil from leaves requires more tools such as mortar, pestle, strainer, cheesecloth, dark bottle, spray bottle, and pot with a lid. You will also need 1 kg of neem leaves, 10 liter of water, and 100ml of liquid soap.
Mash the neem leaves in the mortar and pestle then place the mashed leaves in the container or pot. Pour the water over the mashed leaves into the pot and cover it with a lid. Before you begin the extraction process, you must let the mixture to steep for at least three days for the best result. After three days, take the mashed leaves from the pot by using a strainer. The liquid extracted from them should be clear.
You can use the liquid as insect repellant for plants, but you will have to mix 1 liter of the liquid with 8 liter of water and 100ml of liquid soap. Pour the mixture into a spray bottle so you can easily use it. The remaining liquid should be stored in a refrigerator and used within the next few days before it loses its benefits.
To make shampoo for pets, you can mash a kilogram of neem leaves by using a pestle, pour 5 liter of water into the mashed leaves and let it steep overnight. You can strain the mixture through cheesecloth and use the resulting liquid as shampoo for your pet.
Although many different forms of neem oil are commercially available in most health stores, you can try to manually make the oil by using some simple tools. Overall, traditional extraction method is easy to do and the best thing is that you can use the extraction result for different purposes depending on your needs.
