The invention relates to a Liuwei Dihuang
Pill, which is a famous ancient prescription
medicine applied for about millennium, and is a well selling
medicine for caring health and strengthening body which is pursued by lots of people and frequently taken for a long time; but
Alisma orientale in the Liuwei Dihuang
Pill can cause toxic symptoms such as gastroenteritis,
nausea, emesis, dizzy symptom, giddiness, bellyache, laxness, limbs
weakness, inappetence, pruritus, angioneurotic
edema, allergic eruption, and even respiratory
paralysis, etc. Ancient and recent medicinal literatures indicate that the
Alisma orientale has the effects of dredging the water passage, purging the
kidney-fire and causing dizziness, is unsuitable to be taken for long and overdosed, and serious side effects such as
nephrotoxicity, acute tubular
necrosis, etc., can be caused if the
Alisma orientale is taken for a long time.
Traditional Chinese medicine cortex lycii radicis is the root
bark of medlar that is homology of
medicine and food, and has the same effect of purging the
kidney-fire with the
Alisma orientale in the Liuwei Dihuang
Pill. The invention uses the cortex lycii radicis to replace the
Alisma orientale to be improved into a new Liuwei Dihuang Pill, thereby not only remaining the enriching yin and nourishing
kidney function in Liuwei Dihuang Pill adopting ancient prescription, but also avoiding various side effects caused by using the
Alisma orientale, and facilitating to further increase the medicine safety; the new Liuwei Dihuang Pill can acquire considerable number of market shares in the competition with the original Liuwei Dihuang Pill.
