Abstract Forest resources in northwest Pakistan are under severe threat, negatively affecting local people aiming to meet their subsistence needs through different types of forest use. In addition to uses such as fodder and fuelwood, medicinal plants play an important role in the livelihoods of local people. To reduce pressure and dependency on remaining old-growth forests, some deforested and degraded sites have been reforested. The objectives of the present study were to (1) compare the abundance of medicinal plants on reforested and formerly forested degraded land and (2) assess the influence of reforested stand characteristics on the abundance of medicinal plants. Five plots were randomly selected per land use type. On these plots we analyzed the abundance and other variables of 10 herbal medicinal plants common and important for the rural human population. Frequencies, densities, and cover of the 10 medicinal plants were significantly higher on reforested sites than on degraded sites. Frequencies of highly valuable species such as Valeriana jatamansi, Bergenia ciliata, and Paeonia emodi increased 16-, 8- and 6-fold on reforested sites, respectively. Moreover, density, cover and diversity of medicinal plants (in total) were 7, 5, and 2 times higher, respectively, and 3 species absent on degraded sites were encountered on reforested sites. On reforested plots, tree basal area was the most influential variable positively correlated with the abundance of the aforementioned species. Thus, our data suggest that reforestation of degraded sites can greatly increase the abundance of medicinal plants and may be an instrument for improving the livelihoods of local people and protecting remaining natural forest resources.

β-Glucan is an important functional ingredient having many health benefits. A lot of sources for this valuable ingredient have been identified. β-Glucan from these sources may be extracted to fulfill the ever growing demand for nutraceutical product. The industrialists may also exploit this situation by using this functional ingredient for developing new nutraceutical products. Such products may provide health benefits beyond basic nutrition. Numerous health benefits of β-Glucan are documented in scientific literature that may range from simple stomach problem to complex defense shield against cancer. This review focuses on potential sources of β-glucan, health implications, industrial applications and immunomodulatory effect of β-glucan.

Diversity of Medicinal Plants among Different Forest-use Types of the Pakistani Himalaya Medicinal plants collected in Himalayan forests play a vital role in the livelihoods of regional rural societies and are also increasingly recognized at the international level. However, these forests are being heavily transformed by logging. Here we ask how forest transformation influences the diversity and composition of medicinal plants in northwestern Pakistan, where we studied old-growth forests, forests degraded by logging, and regrowth forests. First, an approximate map indicating these forest types was established and then 15 study plots per forest type were randomly selected. We found a total of 59 medicinal plant species consisting of herbs and ferns, most of which occurred in the old-growth forest. Species number was lowest in forest degraded by logging and intermediate in regrowth forest. The most valuable economic species, including six Himalayan endemics, occurred almost exclusively in old-growth forest. Species composition and abundance of forest degraded by logging differed markedly from that of old-growth forest, while regrowth forest was more similar to old-growth forest. The density of medicinal plants positively correlated with tree canopy cover in old-growth forest and negatively in degraded forest, which indicates that species adapted to open conditions dominate in logged forest. Thus, old-growth forests are important as refuge for vulnerable endemics. Forest degraded by logging has the lowest diversity of relatively common medicinal plants. Forest regrowth may foster the reappearance of certain medicinal species valuable to local livelihoods and as such promote acceptance of forest expansion and medicinal plants conservation in the region.
