The natural substance that is particularly effective in soothing skin irritations and possesses antiseptic properties is sandalwood. Sandalwood has a long history of use in skincare due to its anti-inflammatory qualities, which help to calm irritated skin. Its aromatic oil is often utilized in formulations aimed at promoting skin healing and reducing redness or discomfort.

While other substances listed also have beneficial properties, sandalwood is especially noted for its calming effects on the skin as it can provide relief from conditions like eczema and dermatitis. Additionally, it can help to hydrate the skin, which further enhances its soothing characteristics.

In contrast, peppermint is known more for its cooling sensation and aromatic properties rather than specific soothing effects on irritated skin. Witch hazel is often used for its astringent qualities and can help with minor skin irritations, but it is not as widely recognized for its antiseptic qualities as sandalwood. Tea tree oil is known for its strong antibacterial and antifungal properties and can help with acne and breakouts, yet it may sometimes cause irritation in sensitive skin types due to its potency.

Understanding these distinctions helps clarify why sandalwood is the best choice for this particular question regarding soothing irritated skin.
