Product Information

    Uyaku is the common name for Lindera strychnifolia F. Villar in the Lauraceae family . The use of Uyaku roots is especially important in the traditional phamacopeia of China and Japan for treating kidney deficiencies such as pollakisuria or urinary incontinence . Other well-known uses are; as an astringent, carminative, stomachic, tonic; and as protection against asthma, cholera, congestion, dyspepsia, dysmenorrhea, fluxes, gonorrhea, hernia, malaria, menorrhagia, stomach ache, stroke, and urinary difficulties; as treatment for apoplexy, backache, cancer, gastritis, gastric ulcers, leg ache, polyuria, rheumatism  Uyaku is also thought to have beneficial effects for prevention of aging in general in legendary, though it is not yet clarified.

    Moreover, its fruits are used for treating abdominal distention, dysuria, edema, fungus infections, scabies, and worms; and its seeds are used for antipyretics . Clearly this plant has many potential uses that are worthy of modern scientific investigation.

    The mechanisms of Uyaku’s effectiveness are not known. In the 1990’s, many compounds were isolated from roots of Uyaku, and their structures were determined. These include: linderol (borneol), linderane, linderasure , lindesterene, linderene acetate , isolinderoxide , linderoxide , sesquiterpene lactones , bisesquiterpene , strychnilactone , strychnistenolide and its acetate , and alkaloids]. The well-known Uyaku compounds mentioned above, and other sesquiterpenes such as isolinderalactone, neolinderalactone, lindestrenolide lindenone, linderazulene, chamazulene, laurolitsine, isogermafurene have been summarized in previous other studies . Recent studies demonstrated that Uyaku extract has antiviral activity , an inhibitory effect on prolyl endopeptidase , and is associated with anticancer activity in lungs . It has also a potentially protective effect against post-ischemic myocardial dysfunction , and diabetic nephropathy . In a previous study, we examined whether the water-soluble components of Uyaku leaves have antioxidant activity, and found that root and leaf extracts by hot-water extraction have specific and potent superoxide anion radical scavenging activity as well as several other natural extracts . This is a potentially rich line of research that should be pursued.

    In the present study, we examined the effects of hot-water extract of Uyaku leaves on reactive oxygen species (ROS), reactive nitrogen species (NOS), lipid peroxidation, and protein oxidation.

    you are advised to discontinue use and consult your pharmacist or herbal medical doctor.

    Q: How much water should I boil with how much tea/herb?

    A: Generally you boil 20g of tea/herb with 2L. of water. The ratio does not matter. However, it is recommended that you control the
    saturation of the tea (how strong it is) depending on your personal preference and body condition.

    Q: How do you calculate how much time you should boil water with tea/herb?

    A: It depends on the tea/herb.
    For leaves: boil for 15~20 min.
    For hard fruits, roots, and stems: If you soak the tea/herb in water
    for 1~2 hours before boiling, you can save time in boiling, and also get a deeper flavor than without soaking.

    Q: Do you sell other tea/herbs not listed on the site?

    A: Currently, what is listed on the site is what we mostly deal with in retail stores. However,
    if there is a certain tea/herb that you wish to 
    get, you can send an email to info@princeherb.com. Then, we may offer a price for obtaining the tea/herb, answer questions, and even offer purchase.

    Q: Can you mix household tea/herbs with Princeherb's tea/herbs?

    A: Yes, you can combine 5~10g of teas/herbs that you already have with Princehrb.com's teas/herbs.
    Although brewing one tea/herb is still good, combining 2~3 teas/herbs helps bring out the remedial effects of the tea/herbs better than brewing just one tea/herb. However, most tea/herbs contain natural toxins, and it is recommended that you boil 1~2 pieces of liquorice root along with the tea/herb to remove the toxin.

    Q: What is the direction of Natural Pills & Powder?

    A: Pills : 2-3 times a day / 20-40pills /  Powder : Mix the power with water, milk, rice, or soup. 
        No Caffeine, No Chemical Additives. No Food Color, No Antisepic.
