In recent years, the usage of herbal excipients in medicinal preparations has gained increasing attention due to their biocompatibility, non-toxic nature, and availability from natural sources. As coating materials, herbal excipients provide an eco-friendly alternative to synthetic polymers. These natural materials, derived from plants, are often less expensive, easily accessible, and have minimal environmental impact. The primary role of coating in drug formulations is to protect active pharmaceutical ingredients (APIs) from degradation, mask unpleasant taste, and ensure controlled drug release. Herbal excipients such as gums, resins, mucilage, and essential oils are being explored for their film-forming properties, mechanical strength, and biodegradability. In medicinal coatings, herbal excipients have become a viable and biocompatible substitute for synthetic materials. These plant-based natural coatings are applied to capsules, tablets, and other dosage forms, providing functional advantages such improved stability, controlled medication release, and protecting the environment. Gums (like gum acacia and guar gum), mucilages (like plantago and fenugreek), and resins (like shellac and rosin) are common herbal excipients that that have good film-forming, sticky, and protecting qualities. They are desirable for use in drug delivery systems due to their low toxicity, the biodegradability and combination with active medicinal components. Additionally, herbal excipients can be customized for particular uses, such prolonged release or enteric coatings, which make them adaptable to a range of pharmaceutical needs.
