常见问题和政策

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.

Why do I have a Prop 65 warning on the product I received?

- Proposition 65 is a unique California law that requires manufacturers and businesses to include a warning on any products that contain quantifiable amounts of any one of over 800 possible chemicals, many of which are naturally occurring. Because of the unique nature of this state-specific law which only applies to California, manufacturers, distributors, and businesses are obliged to place a Prop 65 warning on all products which are shipped to California. This warning is the same one that is found throughout hotels, gas stations, airports, golf courses, public parks, and other public buildings found throughout California. This law has been proven by numerous industries as impossible to comply with, and for this reason the Prop 65 warning has often been placed on every product shipped to California.

- Proposition 65 was passed in 1986 with the intention of increasing accountability and preventing people and companies from dumping toxic material in California waters. It is known as "The Safe Drinking Water and Toxic Enforcement Act of 1986," and it enforces the idea that people have the right to know about the presence of dangerous chemicals in their food and water. On a basic level, it is a well-spirited law. However, in practice it is misleading and inconsistent, creating a culture of endless warnings and resource-draining lawsuits.

- Chemicals recognized by the State of California to contain carcinogens or cause reproductive harm are subject to the requirements of Prop 65 and one of the most cited chemicals is lead, which naturally occurs in soil, water, and the ocean. According to Prop 65 the content of lead has particularly stringent regulations, requiring a warning if its presence exceeds 0.5 micrograms in any given product per day. This is nearly 1,000 times lower than the amount known to cause reproductive harm according to the federal government.

- Prop 65 is enforced entirely by way of civil lawsuits brought about by organizations seeking monetary gain in the form of a settlement, and rarely (if ever) is action ever brought by the state's attorney general. This form of litigation puts businesses in a defensive position, forcing them to comply, regardless of the safety of their products. Indeed, Prop 65 warning signs appear all over California, on restaurants, apartment buildings, gas stations, banks, and anywhere else that could theoretically be in violation. Because there is no penalty for over-posting, businesses place warnings as a measure to ensure the safety of their commodities. This results in an ocean of vague and faulty information, hiding shady business practices while vilifying the compliant.
