One of the most important considerations in treating herbal ingestions is product quality assurance. Although most herbal companies are reputable, there are numerous reports of adulterated products (addition of substances not noted on the label). This has been particularly true of Chinese herbal products, which frequently contain pharmaceutical agents. Plant identification errors occur, and entire batches of product have been mixed using the wrong herb. In some cases, labels are written in a foreign language or only contain directions for mixing, making interpretation difficult. In cases where a known ingestion produces unexpected clinical signs, the potential for adulteration or other errors should be considered. When a product is not standardized, a consumer cannot be sure what dose of active constituents has been used or how bioavailable the product may be. Standardization also provides assurance that the actual herb is in the product [26]. Clients who use herbal products should be advised to treat them as a medication and to keep them away from pets. Specifically, ask clients if they take or use any natural or herbal products. Many people do not consider these substances drugs or assume, "If natural, it is harmless." Clients should be encouraged to learn about the herbal and neutraceutical products they are taking or giving their pets. Owners need to discuss the proper use of herbal products in pets with their veterinarian. Clients can be encouraged to discuss alternative therapies by discussing a pet's diagnosis and suggested treatments thoroughly. Discuss the client's expectations and opinions of alternative and conventional medicine. Issues of safety and efficacy must be fully explained to clients. Clients should be encouraged to report potential adverse reactions or to discuss different routes of therapy if a pet's medical condition is not improving. Clients who want to use alternative medical treatments should obtain a thorough medical workup so as to make a correct diagnosis and be referred to a veterinarian trained in alternative medicine. In choosing an alternative medicine practitioner, the same criteria would be used as for any other specialist: education, training, and professionalism [14].
