Effect of French Marigold (Tagetes patula Linn.) against Head Lice (Pediculushumanuscapitis)

Abstract

The objective of this study was to test the Effect of French Marigold ( Tagetes
patula Linn.) against the adlice (Pediculushumanuscapitis) at 24 hours with contact
method. The experiment was repeated four within 24 hours (n=100) using French Marigold
from root trunk leaf and flower which were extracted with 95% ethylalcohol with
marceration for 7 days to extract the amount of α-terthienyl of marigold plants roots, stems,
leaves, and flowers found at most equal to 7.665 mg-per-g. Followed by the flower, stem
and leave is equal to 3.278 mg-per-g, 0.904 mg-per-g, 0.196 mg-per-g, respectively. Extract
the 4 parts contribution kill to the lice die at the most is an extract from the root. By
60.4%, making lice die within 24 hours. The second is an extract from the flowering stem
and leaves, making lice died, 44.4%, 29.6% and 27% within 24 hours, respectively. The 50%
lethal dose (LC50) from the roots and stems. Leaves were 0.06247, 0.10506, 0.15811 and
0.19008 ppm Thus leading contribution to the lice die extract is an extract of the roots as
possible to try to kill of head lice in adults in the community and in the laboratory. Head
lice found that adults in the community was 85, the figure was 85 percent. The head lice
larvae in the laboratory was 81 to 81 percent, respectively, within 24 hours, also found.
Marigold extract from the root cause of adult death, head lice are not significantly different
(p=0.2665). The experiments showed that extract less. Effective in eliminating head lice is
best. Extracts from the roots. The roots should be used to get rid of head lice in children
with head lice, instead of using chemicals.
