Flowers in clusters, female ones above, male ones below, July to September. Seed capsule has soft spines. The flowers have no petals and grow in upright panicles covered with dark brown spines. The fruit which follows is a capsule containing 3 large seeds. The dark shiny seeds are extremely poisonous if swallowed, but can be easily removed from the plant when they first begin to form. Because castor bean is extremely sensitive to frost, seed must be started indoors in early spring in cooler climates, or outdoors only in warm ground. Space plants 3-4 feet apart in full sun. Adaptable to most soils, adding fertilizer will give brightest color and faster growth. Plants like lots of water, which mulching will help conserve. Do not pinch or tip-prune castor bean, this may kill the plant. While spider mites may be a problem on indoor seedlings, they usually disappear when the plants are set outdoors. Prefer good drainage, lots of water, will grow in clay or sandy loam. Varieties Carmencita and Dwarf Red Spire have attractive red foliage. Ricinus africanus has very large green leaves, R. macrocarpus has purple-red foliage: R. cambodgensis has blackish-purple stems and leaves, R. sanguinea is red-leaved, and R. gibsonii, a lovely dwarf, has dark red leaves with a metallic luster.

Sal-Plant Gel

Treats skin problems, such as acne, psoriasis, or seborrheic dermatitis. Some forms of salicylic acid are used to remove warts.



20, 21, 22, 23 Allergenic extracts are indicated for use in diagnosis and immunotherapy of patients presenting symptoms of allergy (hay fever, rhinitis, etc.) to specific environmental allergens. The selection of allergenic extracts to be used should be based on a thorough and carefully taken history of hypersensitivity, and confirmed by skin testing.24, 25 The use of mixes of unrelated antigens for skin testing is not recommended since, in the case of a positive reaction, it does not indicate which component of the mix is responsible for the reaction, while, in the case of a negative reaction, it fails to indicate whether the individual antigens at full concentration would give a positive reaction. Utilization of such mixes for compounding a treatment may result, in the former case, in administering unnecessary antigens and, in the latter case, in the omission of a needed antigen. Statistically controlled blind studies have demonstrated the effectiveness of therapy with Amb a 1.26 However, double blind studies have demonstrated a greater effectiveness for whole Short Ragweed extract when compared to Amb a 1 alone.27 Short Ragweed Extracts, standardized on the basis of Amb a 1 extract, would seem to be a logical choice for immunotherapy. Allergens to which a patient is extremely sensitive should not be included in treatment mixes with allergens to which there is much less sensitivity, but should be administered separately. This allows individualized and better control of dosage increases, including adjustments in dosage becoming necessary after severe reactions which may occur to the highly reactive allergen.
