A: Our formulas are available in either capsules, granules or tablets. Please note that some formulas might not be ready-made in your preferred form. We would ask you to place a special formula order in such a case.
A: There are no minimum order quantities for stock (standard) items. Regardless of your size, your professional discounts remain the same. This is our way of appreciating your business.
A: With the exception of TCM books, all TCM products require a valid health care provider license. A valid health care provider is an individual who is authorized to prescribe and administer herbs. Proof of license or certification is required.
A: Patient safety is our utmost priority. We reserve the right to refuse to sell any of the products to our customers if there are any concerns that the patient's health may be adversely affected.
A: We take pride in maintaining reasonable prices but due to fluctuations in world-markets, currency exchange rates and other factors beyond our control, prices are subject to change without notice. Please regularly check our site for the latest up-to-date prices.
A: Our general cut-off time for same-day shipping is 1:00 PM Pacific Time (PT) for orders shipping via FedEx or UPS, provided the order is received on a business day and items are in stock.
Important USPS Exception: Orders shipping via USPS follow a different schedule due to morning-only carrier pickup:
USPS orders placed after the morning pickup will ship on the next business day.
USPS does not pick up on weekends.
Orders placed over the weekend will be processed on Monday; however, if received after the USPS morning pickup, they may ship on the next business day, especially during periods of high order volume.
Additional Notes:
Business days are Monday–Friday, excluding holidays.
High order volume, weather delays, or carrier constraints may occasionally impact shipment timing.
“Prepared for shipment” means your order has been packed and labeled; actual carrier pickup depends on carrier schedules.
If same-day shipment timing is critical, we recommend selecting FedEx or UPS expedited services at checkout.
A: Unopened products can be returned for credit within 90 days of purchase after you have contacted us for a return authorization number. Please have your invoice number ready when calling for a return. Returned products are subject to a 15% restocking fee.
The name change on the labels aligns with the US Food and Drug Administration (FDA) requirements to provide more accurate and comprehensive information to consumers regarding the product/ingredient composition.
Not necessarily. While the name on the label has changed to comply with FDA regulations, the product/ingredient itself remains the same. We are committed to maintaining the quality and standards that you have come to expect.
The name change does not affect the safety and quality of the product/ingredient. It is implemented to provide more precise information and ensure regulatory compliance without compromising quality.
Absolutely. The change is designed to enhance clarity and transparency for consumers, helping you to make informed decisions while maintaining the trust and confidence you have in our products.
Yes, the availability of the product/ingredient will not be affected due to the name change. You can continue to find it at your preferred retailers and online platforms.
No, the usage of the product remains the same. The name change is to ensure adherence to regulatory guidelines and to offer you more clarity about the product/ingredient composition.
A: The United States Pharmacopeia (USP) provides guidelines for heavy metal testing and standards to limit elemental contaminants in dietary supplements. The USP standard, effective from January 1, 2018, replaced the century-old USP method, introducing advanced techniques for elemental contaminant determination. The primary focus is on four elements of toxicological concern: arsenic, cadmium, lead, and mercury. The Permissible Daily Exposure (PDE) limits are arsenic (inorganic) 15 µg/day, cadmium 5 µg/day, lead 5 µg/day, mercury (total) 15 µg/day. These limits ensure more accurate, precise, and quicker results, while also considering unexpected elemental contaminants for better compliance.
We are currently piloting a limited run of finished, packaged granules received from Taiwan. Because these bottles were labeled and packaged in Taiwan, you may notice small visual differences compared to our usual U.S.-labeled bottles, such as:
Slight variations in label color tone, fonts, and information layout
The product name printed (stenciled) on the cap in Chinese.
Manufacturing date, expiration date, and batch/lot information printed in a different location or format (sometimes alongside a QR code)
Shelf-life / date labeling note: U.S. bottles typically list the manufacturing date only. For U.S. customers, Sun Ten uses a 3-year shelf-life guideline from the manufacturing date when stored properly (cool, dry, tightly closed). Taiwan-packaged bottles may also include an expiration date on the label as part of Taiwan’s standard format. Some Taiwan-packaged bottles may show a 2-year shelf life on the label. This reflects Taiwan’s standard labeling convention. If you have any questions about the dates shown on your bottle, please contact us with the product code and lot number and we can confirm.
These differences are cosmetic only. The product inside is still authentic Sun Ten herbal extract granules, produced to Sun Ten’s established quality standards.
Yes, our products are gluten-free. We do not use any gluten-based ingredients in our formulas. Only formulas containing Fu Xiao Mai, Mai Ya or Shen Qu are gluten based.
A: Yes. Safety is a top priority at Sun Ten. Our bottles are made from HDPE (#2) with PP (#5) caps—durable, widely recyclable materials commonly used for food and dietary supplement packaging.
Color safety: We use insoluble pigments (not liquid dyes) designed for food-contact plastics. Our pigments meet applicable safety standards, including compliance with RoHS and REACH SVHC requirements, and contain no intentionally added lead, cadmium, mercury, or hexavalent chromium.
Why yellow (not white): Opaque yellow provides better light blocking than white or natural HDPE, helping preserve light-sensitive herbal constituents and product stability throughout shelf life.
Sustainability: HDPE and PP are accepted in many curbside recycling programs.
Yes, Prima Nova Botanicals utilizes maltodextrin as an excipient in its single herb granules, diverging from Sun Ten’s traditional use of non-GMO corn starch in their products.
