Is Herbal Medicine safe?
Practitioner-guided herbal medicine with quality-tested extracts and independent third-party testing.
Our Standards
Every Poppy formula is reviewed by a licensed practitioner and blended to order by U.S. pharmacy partners using quality-tested, whole-herb extracts from manufacturers that follow current Good Manufacturing Practices (cGMP).
Each batch is accompanied by a Certificate of Analysis confirming herb identity and purity, with screening for heavy metals, pesticide residues, and microbial contaminants. Together, these safeguards support consistent quality, purity, and clinical oversight.
Practitioner Oversight
Every formula is reviewed for safety by a U.S.-licensed practitioner trained in Traditional Chinese Medicine (TCM) and herbal medicine. Practitioners evaluate your health history, current medications, and potential herb–drug interactions to ensure each formula is appropriate and safe for ongoing use.
Poppy works with practitioners who hold national board certification through the National Certification Board for Acupuncture and Herbal Medicine (NCBAHM), reflecting standardized training in herbal medicine and clinical practice.
Our Process
Held to Rigorous Quality Standards
Every formula is sourced, reviewed, and prepared through partners held to strict quality and safety requirements.
Herb Processing Standards
Formulas prepared for Poppy follow controlled manufacturing standards and are produced in sealed, temperature-controlled environments.
During extraction, only purified, softened water is used to preserve the integrity of each herb.
Contaminants & Microbial Safety
Our sourcing partners test every batch of herbs for common environmental contaminants, including pollutants, insecticides, fungicides, herbicides, and pesticides, before ingredients are approved for use.
Heavy Metal Safety
Poppy works exclusively with manufacturers whose herb extracts are individually tested for heavy metals, including arsenic, cadmium, lead, and mercury.
Solvent-free processing
Our partners adhere to strict solvent-free processing standards, including:
- No acetone
- No hexane
- No industrial solvents of any kind
Microbial testing standards
Microbial testing is conducted by partner laboratories in accordance with U.S. Pharmacopeia (USP) guidelines.
Herbs are screened for organisms such as:
- E. coli
- Salmonella spp.
- Enterobacteriaceae
- And other harmful microbes before approval for use.
Testing includes internal quality controls and independent third-party laboratory testing conducted in the U.S. prior to compounding.
Validated laboratory testing
Our partners ensure each metal is evaluated independently using scientifically validated analytical methods aligned with U.S. Pharmacopeia and World Health Organization (WHO) standards.
Batches that do not meet these standards are rejected.
How Herbal Products Are Regulated
Dietary supplements
Many herbal products sold in the U.S. are regulated as dietary supplements and must follow FDA current Good Manufacturing Practices (cGMPs) for quality, purity, and safety.
Customized or practitioner-guided formulas
Herbal formulas customized or modified for an individual may be prepared and dispensed differently from over-the-counter products. At Poppy, formulas are prepared for an individual following review by a licensed practitioner and are not offered as one-size-fits-all products. Poppy’s care model is built around individualized, practitioner-guided formulations.
Clinical-grade herbal care
Poppy works exclusively with clinical-grade herbal formulas delivered through licensed practitioners and U.S. pharmacies. This model supports appropriate clinical oversight, reduces the risk of misuse, and ensures care is delivered within FDA and state practice standards.
Why safety matters
Herbal medicine can be highly effective—but like any meaningful treatment, it requires clinical judgment. Herbs may be natural, but they are also potent, and the right formula depends on the individual, their health history, and how herbs may interact with medications or other considerations.
That’s why every Poppy formula is reviewed and designed by a licensed, board-certified herbal practitioner. Formulas are selected, combined, and adjusted thoughtfully to support safety and long-term care.
Frequently asked questions
Are herbs safe to take with other medications or supplements?
Herbal medicine may be used alongside other medications or supplements in some cases, but it is important to provide complete and accurate information about everything you take. Your practitioner reviews your health history, medications, supplements, and treatment goals to help identify potential interactions or contraindications and determine whether personalized herbal care is appropriate. Never stop, start, or change prescribed medication without guidance from the clinician who manages that medication.
Who designs my formula?
Poppy formulas are designed and reviewed by licensed practitioners with active U.S. state licensure and NCCAOM board certification in Chinese Herbology (Dipl. C.H.) or Oriental Medicine (Dipl. O.M.). Each practitioner has formal training in Chinese herbal medicine and clinical experience in pattern differentiation, formula design, and ongoing modification. Every formula is reviewed by a practitioner before it is prepared.
Why do herbal formulas require practitioner review?
Herbal formulas are not one-size-fits-all. Herbs contain active compounds, and the herbs, combinations, preparation, and dosing that may be appropriate for one person may not be appropriate for another.
A practitioner reviews your symptoms, full health history, medications, supplements, and current needs to help identify potential interactions or contraindications and determine whether herbal care is appropriate. Review also helps ensure that your formula is selected, dosed, and adjusted thoughtfully over time.
Are herbs tested for safety?
Yes. All herbs used in a Poppy formula are tested for purity, potency, and safety, including screening for pesticides, pollutants, microbial contaminants, and heavy metals.
Each herb undergoes multiple layers of testing—including independent third-party testing in the United States. Only batches that meet strict quality standards are used in formulas.
Are herbs tested for heavy metals?
Yes. Our herbal extract suppliers test for individual heavy metals—including lead, mercury, arsenic, and cadmium—using scientifically validated methods aligned with U.S. Pharmacopeia (USP) and World Health Organization (WHO) standards.
