Herbal blends have long been used traditionally to manage canker sores (aphthous ulcers), particularly in various systems of traditional medicine such as Ayurveda, Traditional Chinese Medicine, and folk remedies worldwide. These blends may include ingredients like licorice root, chamomile, myrrh, sage, and other botanicals reputed for their anti-inflammatory, antimicrobial, or soothing properties. For example, licorice root (Glycyrrhiza glabra) has been shown in some small studies to reduce pain and healing time of canker sores when applied topically. Chamomile and myrrh have also been used as mouth rinses for their purported healing effects on oral mucosa. However, most commercial "herbal blends" are proprietary and do not disclose exact ingredient composition or concentrations, making it difficult to evaluate efficacy or safety rigorously.

While there is some preliminary scientific evidence supporting the use of certain herbs individually, robust, high-quality clinical trials specifically examining proprietary herbal blends for canker sores are lacking. Most evidence remains anecdotal or based on traditional usage rather than systematic research. Therefore, while the traditional use of herbal blends for canker sores is well-established, scientific validation—especially for proprietary mixtures—is limited, and efficacy may vary depending on the specific herbs and their preparations.
