The active ingredients found in the leaves of chaparral can be made into a warm tea for internal use or sun tea for topical applications. Use about 7-8 grams (quarter of an ounce) of bulk tea to a quart of water. If taking internally, drink at least three cups a day. At this strength, one pouch of tea will last about three to four weeks. Long-term use is not recommended.
Chaparral leaf can also be powdered and made into a paste and pressed against teeth that are causing pain or that have decay. If using this Native American approach, be prepared for a rather peculiar taste that many find disgusting. There is a reason this plant is often called creosote bush.
