Frequently Asked Questions

How do I cook my herbs?
- Each herbal formula is different based on the volume of herbs but most can be cooked with 5 cups of water and reduced down to about 1-2 cups of brew (Around 45 minutes of cook time when put on medium heat after bringing to a boil). Depending on the quantity of herbs, the amount of water put in should be adjusted. Please consult your herbalist for a more detailed answer to your specific formula.

Where can I get an herbal formula?
- There are many traditional herbal formulas in TCM (Qing Bu Liang, Shi Quan Da Bu Tang, Qing Fei Pai Du Tang) but each individual responds differently to different formulas. We recommend consulting with an herbal practitioner to put together an herbal formula specific to you and we can help you fill it. Additionally, you can conduct research on some of the common ones and try them to see how they work for you.

I don't see the herb that I want. Is there any way you can get it for me?
- Yes! We have a wide variety of herbs in stock (almost 500 kinds with some having multiple forms such as powder or seeded) and are working on getting them online. However, in the meantime we’ve provided some of our most popular ones in our current online store. If you don’t see the herb that you’re looking for, don’t hesitate to contact us through any of the methods above. Its common name, scientific name, Chinese name, or even picture will all help in determining what the herb is and whether we have it.

How many times can I cook my package of herbs?
- Each package of herbs can be brewed up to 2 times. You could brew it additional times but each subsequent brew will be more diluted than the one before. We recommend adding some honey to sweeten up the brew if the taste is a bit hard to bear.
