    1) Preferred sedative hypnotic drug that treats chronic sleeplessness. Thanks to its inhibition of certain central nervous system, it is not only sedative and hypnotic, but also aromatic and expectorant. That’s to say, it has a good effect on insomnia disorder caused by the interference of phlegm-heat. What’s more, it also has sedative and hypnotic effects for the mentally ill;

    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.
