Extracts made from the
leaves of Hypericum perforatum are used in herbal medicine for treating
depression. The species is used in herbal medicine to treat many other diseases
as well, although it is toxic to sheep and cattle.

Hypericum perforatum is found in the
Hula Valley, the northern Golan Heights and the Mount Hermon foothills at eight
documented sites, although there are an estimated ten sites. In the Hula Valley,
it is found in Sahlavim Nature Reserve in Hurshat Tal National Park, in the Hatsbani
and En Dan. In northern Golan Heights, it grows on three sites in the area of the
Odem Forest and at the Banias. In the lower Hermon, it is found in the Yafori
valley.

In Israel Hypericum perforatum appears in two completely different habitats: grassy areas on spring
margins and open woodland.

·        
Some of the Hypericum perforatum sites are accessible
and are threatened by agricultural development. The small population size
constitutes a demographic threat. Its habitat – wetlands – is threatened by
desiccation and pollution due to the decrease in groundwater levels caused by
over-pumping
.

·        
H. perforatum is protected in
the Hurshat Tal and Mas’ada Forest reserves
.

·        
The species has a broad global
distribution and is not globally endangered. 

Additional
surveys are needed to confirm the information regarding its distribution sites
in the Hula Valley and the Golan Heights and to monitor the populations found. A
site should be demarcated in HurshatTal and the Hula Valley where
H. perforatum will be
protected. Cuttings should be made to propagate the species in refuge gardens
and in gardens in the reserves in which it grows.

Hypericum perforatum is found
throughout Europe including the British Isles and North Africa, the Azores Archipelago,
the Madeira Islands and western Asia. It was brought into many areas of the
world and spread in the wild. In some countries, it is considered a noxious weed
and an invasive species.

Hypericum
perforatum
is
a rare herbaceous perennial species that grows on vulnerable sites. The species
grows in many parts of the world and used as a medicinal herb; it is not globally
endangered.
