How Post-harvest management is done in Growing Holy Basil?

After cutting the crop, it has been allowed to wilt in the field for 4 hours for minimizing the moisture level in the leaves. Leaving the crop for a long time after harvest (more than 8 hours) may drastically reduce the quality of oil and yield. Steam distillation is used extract the oil and the oil is decanted and filtered. The distilled tulsi oil is treated with common salt @ 20 grams/litre oil to remove the moisture content. Usually, the filtered oil is stored in cool and dry place in glass bottles or clean containers.
