Roughing it’s one of the best ways to spend a vacation. Immersing yourself in the great outdoors is the only way to enjoy Mother Nature’s splendor. To make sure the trip turns out great, one must bring a complete first aid kit. No matter how careful he is, there’s no guaranteeing that the unknown won’t leave him alone. For instance, you might brush against some poison ivy, poison oak, or poison sumac, causing you to break out in terrible rashes. If you forgot to bring a treatment for skin irritation, your trip will be ruined. An over-the-counter treatment for skin irritation is calamine lotion. This topical medication is available at most local stores, come in small, plastic, screw-top bottles, and is affordable (e.g., a 6 oz bottle of the lotion costs, more or less, $8.00). But wouldn’t it be better to make some calamine lotion yourself? If you think so, too, you could, by way of bentonite clay.
