| | Plant Patents: Larrea Tridentata. |
 | | Nontoxic extract of Larrea tridentata and method of making same. |
 | | A nontoxic, therapeutic anti-inflammatory and antiviral agent is made from a concentrated extract of Larrea tridentata (chapparal) plant material made with one of several specified reducing agents (including, among others, ascorbic acid, an ascorbic acid ester, an ascorbic acid salt, a tocopherol, or vitamin E). |
 | | The reducing agent reduces the toxic nordihydroguaiaretic acid (NDGA) quinone, which naturally occurs in chapparal, to nontoxic NDGA, and additional quantities of reducing agent inhibit the natural oxidation of the NDGA into the toxic NDGA quinone in vivo, during processing, or during storage. |
