China H&Z® Andrographolide is the whole grass or leaf of andrographis paniculata. Have clear heat detoxification, diminish inflammation, reduce swelling analgesic effect. It is mainly used for treating bacillary dysentery, urinary tract infection, acute tonsillitis, enteritis, pharyngitis, pneumonia and influenza, etc. Mainly produced in Guangdong, Fujian and other provinces, central China, North China, northwest and other places also introduced.

China H&Z® L-Pyroglutamic Acid (also known as PCA, 5-oxoproline, pidolic acid, or pyroglutamate for its basic form) is a ubiquitous but little studied natural amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam.It is a metabolite in the glutathione cycle that is converted to glutamate by 5-oxoprolinase. Pyroglutamate is found in many proteins including bacteriorhodopsin. N-terminal glutamic acid and glutamine residues can spontaneously cyclize to become pyroglutamate, or enzymatically converted by glutaminyl cyclases. This is one of several forms of blocked N-termini which present a problem for N-terminal sequencing using Edman chemistry, which requires a free primary amino group not present in pyroglutamic acid. The enzyme pyroglutamate aminopeptidase can restore a free N-terminus by cleaving off the pyroglutamate residue.

Alpha lipoic acid of H&Z® factory is light yellow powder, almost odorless, alpha lipoic acid easily soluble in benzene, ethanol, ethyl , chloroform and other organic solvents.Alpha lipoic acid almost insoluble in water, the water solubility: 1 g/L (20 ℃) soluble in 10% NaOH solution.
Alpha lipoic acid is a coenzyme found in mitochondria, similar to vitamins, which eliminates free radicals that cause accelerated aging and disease. Lipoic acid enters cells after it is absorbed through the intestinal tract in the body and has both lipid-soluble and water-soluble properties.

Methylsulfonylmethane (MSM) is an organosulfur compound with the formula (CH3)2SO2. It is also known by several other names including DMSO2, methyl sulfone, and dimethyl sulfone.[1] This colorless solid features the sulfonyl functional group and is considered relatively inert chemically. It occurs naturally in some primitive plants, is present in small amounts in many foods and beverages, and is marketed as a dietary supplement.
