[What is Huperzine A]

Huperzia is a type of moss that grows in China. It is related to club mosses (the Lycopodiaceae family) and is known to some botanists as Lycopodium serratum . The whole prepared moss was used traditionally. Modern herbal preparations use only the isolated alkaloid known as huperzine A. Huperzine A is an alkaloid found in huperzia that has been reported to prevent the breakdown of acetylcholine, an important substance needed by the nervous system to transmit information from cell to cell. Animal research has suggested that huperzine A’s ability to preserve acetylcholine may be greater than that of some prescription drugs. Loss of acetylcholine function is a primary feature of several disorders of brain function, including Alzheimer’s disease . Huperzine A may also have a protective effect on brain tissue, further increasing its theoretical potential for helping reduce symptoms of some brain disorders.

[Function] Used in alternative medicine, huperzine A has been found to act as a cholinesterase inhibitor, a type of medicine used to prevent the breakdown of acetylcholine (a chemical essential to learning and memory).

Not only used as a treatment for Alzheimer’s disease, huperzine A is also said to enhance learning and memory and to protect against age-related cognitive decline.

In addition, huperzine A is sometimes used to boost energy, increase alertness, and aid in the treatment of myasthenia gravis (an autoimmune disorder that affects the muscles).

Aphids inflict serious damage to a variety of crops. They are notorious virus vectors and have an enormous reproductive capacity.
There are lots of different coloured species and they occur in all kinds of crops. The nymphs and adults extract food materials from the plant and disturb the balance of the plant’s growth hormones.
It can result in deformed leaves or even the death of young plants. Aphids secrete honeydew which is a nutrient source for sooty moulds. Their saliva can also induce strong allergic reactions such as malformations of the growing tips. The aphid in this video is the most important vector of viruses and is thus feared by many growers. When reproduction is asexual, the young aphids are born as developed nymphs. They immediately start to feed on plant sap and grow rapidly. Aphids moult four times before reaching adulthood.
With each moult they shed white skin, betraying their presence in the crop. Adult aphids can have different appearances. They can vary in colour and can be winged or wingless. The most effective method to control aphids depends on species, crop and climate.
