Scientific name: Gliricidia sepium
Family: Leguminosae

Madre de cacao is a nitrogen-fixing tree. In some areas, it is referred to as a quick-stick due to its characteristic of growing almost right away just by cutting it and directly planting it in the ground. It is a fast growing tree with a maturity height of 10 meters (33 feet). It is adaptable to almost any soil environment, including infertile soils. It is tolerant to salt spray and water logging. It can tolerate drought for up to 6 to 8 months. This tree can be potentially weedy, but rarely causes a problem. Its ubiquitous characteristic makes it a good alternative for feeds due to its availability in almost all areas in the country.

Standard procedures for the preparation and application of the plant extracts

1. Select plant parts that are free from diseases.
2. When storing the plant parts for future usage, make sure that they are properly dried and are stored in an airy container (never use plastic container), away from direct sunlight and moisture. Make sure that they are free from molds before using them.
3. Use utensils for the extract preparation that are not use for your food preparation and for drinking and cooking water containers. Clean properly all the utensils every time after using them.
4. Do not have a direct contact with the crude extract while in the process of the preparation and during the application.
5. Make sure that you place the plant extract out of reach of children and house pets while leaving it overnight.
6. Harvest all the mature and ripe fruits before plant extract application.

8. Wear protective clothing while applying the extract.
9. Wash your hands after handling the plant extract.
